Everything Microsoft CSPs and MSPs need to know: M365 E7 general availability, Dragon Copilot repricing, License Mobility for server workloads, Tax ID modernisation, price list corrections — and the deadlines you cannot afford to miss.

Critical Deadlines and Actions

• May 2, 2026 [Updated] - New Commerce Price List Correction — Download the Updated Files: The May 1 price lists published with incorrect effective end dates (5/4/2026) have been corrected. Extended Service Term (EST) price lists were also missing SKU line items. Updated files are now available as of May 2. No actual price changes — purely a data correction. Partners should verify they have the May 2 version.
• May 1, 2026 [GA Now] - Microsoft 365 E7 & Agent 365 — Generally Available: The Frontier Suite is live. M365 E7 bundles E5, Copilot, Entra Suite, and Agent 365 into one SKU. It's on the CSP price list today. Begin upsell motions with existing E5 customers immediately — launch promotions of up to 15% off are available through December 31, 2026.
• May 1, 2026 [Live Now] - Dragon Copilot Reduced Pricing & End of Physician Practice SKU: Dragon Copilot per-user list price drops across all 10 geographies. The Physician Practice offer reaches end of sale. New simplified per-encounter consumption model goes live. Update sales materials and quote workflows before customers come to you with pricing questions.
• Apr 1, 2026 [Live Now] - License Mobility for Windows Server & SQL Server Subscriptions: CSP subscription customers under MCA now have License Mobility rights equivalent to Software Assurance — automatically, with no action needed. Applies to subscriptions only, not perpetual licences. Update your sales scripts to reflect this new value-add.
• Apr 1–13, 2026 [Live Now] - Global Tax ID Modernisation — Validate Your Tax IDs in Partner Center: Microsoft has updated how Tax IDs are collected and validated across all geographies. Partners in Brazil, India, Italy, Egypt, and Serbia may need to supply multiple Tax IDs. Log in to Partner Center → Account Settings → Legal Info → Bill to Info and verify your records now. Missing or incorrect Tax IDs can cause billing disruptions.
• May 4, 2026 [Live]- Extended Service Terms (EST) Full Enforcement: Subscriptions purchased on or after Apr 1 2025, expiring on or after Apr 1 2026, with auto-renew off — automatically move to EST. Billing is at standard monthly rate + 3% uplift. Use Partner Center's EST download to audit your base before this date.
• Jul 1, 2026[Plan Now] - Microsoft 365 Global Price Increase — Lock In Renewals Now: Price increases apply to new and renewing M365 customers globally across Business, Enterprise, and Frontline plans. Customers who renew before July 1 lock in current pricing. Run your renewal report using CloudAscent today and begin proactive conversations.

What Are the Key Updates for Microsoft Partners?

This combined edition covers announcements from late April and the first two weeks of May 2026. We've also included relevant April catch-up items that continue to have operational impact through May.

April 2026 — Key Announcements (Catch-Up)

These April announcements were published on April 1 and continue to have direct impact on your operations, billing, and sales motions through May and beyond.

Dragon Copilot Reduced Pricing — New Consumption Model

Published April 1, effective May 1, 2026: Microsoft has reduced the Dragon Copilot per-user list price across all 10 geographies where it's offered — US, Canada, Ireland, UK, Austria, Germany, France, Netherlands, Belgium, and Switzerland. The Physician Practice SKU reaches end of sale on May 1, consolidating customers into the standard per-user licence at the new, more competitive price point.

Additionally, the consumption model for ambient encounters and generative AI capabilities is being simplified: fees are now applied per encounter rather than per individual ambient note or AI action. This is significant for healthcare-focused CSPs and partners building Dragon Copilot practices around clinical settings.

Action Required

• Update Dragon Copilot pricing in your quoting tools and customer-facing materials before May 1.
• Identify Physician Practice SKU customers and plan migration to the standard per-user licence.
• Contact your account representative for the updated Dragon Copilot Partner Assets page materials (available May 1).
• Re-engage stalled healthcare pipeline conversations with new pricing.

License Mobility for Windows Server & SQL Server Subscriptions

Effective April 1, 2026, Windows Server and SQL Server subscriptions purchased through CSP under the Microsoft Customer Agreement (MCA) include License Mobility rights — automatically, without any action required from partners or customers. This grants rights equivalent to Software Assurance in legacy Volume Licensing.

In practical terms: customers can now run eligible server application workloads in shared environments and with authorised outsourcing partners. This is a meaningful simplification that removes a key objection in migration conversations where customers were reluctant to move from traditional VL agreements to the new commerce experience.

This applies to subscriptions only. CSP perpetual licences remain unchanged and do not gain License Mobility rights. Make sure your sales and pre-sales teams understand and communicate this clearly to avoid customer confusion or inaccurate commitments.

Action Required

• Update your Windows Server and SQL Server sales scripts and customer-facing materials to include License Mobility messaging.
• Differentiate clearly: subscription = License Mobility included; perpetual = no change.
• Review the updated product terms and partner FAQ from Microsoft partner resources.
• Re-engage customers still on legacy VL agreements for server workloads — the migration case just got stronger.

Microsoft 365 E7 — SKU Transactability & Launch Promotions Preview

The April 1 announcement confirmed the full commercial terms for Microsoft 365 E7's CSP availability starting May 1, 2026. E7 is available on monthly, annual (one-year), and triennial (three-year) terms. Price list preview for one-year terms was available from April 1.

Launch Promotions (available through December 31, 2026):

Action Required

• Identify your top E5 customers — these are the primary E7 upsell targets.
• Download the E7 launch guide at aka.ms/ME7LaunchKit and the Global Promo Readiness Guide.
• Brief your sales team and build customer pitch decks using the partner launch kit materials.
• Set up internal ordering workflows for May 1 transactability.
• Monitor for promo activation confirmation — promos may have a slight delay post May 1.

Global Tax ID Modernisation — Partner Center Account Update Required

Rolling out between April 1 and April 13, 2026, Microsoft has overhauled how Tax IDs are collected, validated, and stored across all countries and regions. The update introduces country/region-specific Tax ID types that dynamically adjust to local requirements, and supports multiple Tax IDs where local law requires it.

The update covers two access points in Partner Center depending on your programme membership:

• MAICPP members: Partner Center → Account Settings → Billing Profile
• CSP Direct/Indirect Providers: Partner Center → Account Settings → Legal Information → Bill to Info

Action Required

• Log in to Partner Center and review your Tax ID details in the appropriate billing or legal profile section.
• Partners in Brazil, India, Italy, Egypt, or Serbia: check for newly required additional Tax ID fields.
• Ensure all mandatory Tax ID fields are complete and accurate to avoid billing disruptions.
• Submit a support ticket via Partner Center for navigation or operational questions — do not rely on phone support for this.

April 2026 — New Announcements

These items were announced during April and remain operationally active or require action through May. They have been included here because their deadlines or impact windows extend into mid-May and beyond.

MFA Enforcement for Partner Center App+User APIs — Now Live

Since April 1, 2026, all Partner Center app+user API calls without a valid MFA claim are blocked and return a 401 response with error code 900421. This follows the MFA rollout to the Partner Center portal in August 2025 and extends those protections to all API-level access.

Immediate Action Required

• Audit every system that calls Partner Center APIs using app+user authentication.
• Update each system to include a valid MFA token in the Authorization header of every API request.
• Test updated integrations in the Partner Center sandbox before pushing to production.
• Review Microsoft's MFA requirements guide at learn.microsoft.com for supported authentication flows.

Reference Id JSON Format Change in Reconciliation Files — April 15

Effective April 15, 2026, the ReferenceId attribute in both Billed Reconciliation and Unbilled Reconciliation files changed from a plain string to a structured JSON object that includes both an identifier and a version field. This improves consistency when correlating reconciliation records across billing systems.

Action Required — Check Status Immediately

• Verify whether your reconciliation processing has been updated to parse ReferenceId as a JSON object (not a plain string).
• Test your reconciliation pipeline against real files from Partner Center to confirm no parsing errors exist.
• Check downstream BI dashboards or billing reports for any anomalies introduced after April 15.

Sri Lanka VAT — 18% on Digital Services (Effective April 1)

Under Sri Lanka's VAT Act (Amendment) No. 4 of 2025, all digital services invoiced from non-resident companies to Sri Lankan customers are now subject to 18% VAT effective April 1, 2026. Partners and customers in Sri Lanka who have not already submitted a valid VAT ID to Microsoft should do so via the Partner Center billing profile section.

Action for Sri Lanka Partners & Managers

• Register a valid Sri Lanka VAT ID in Partner Center's billing profile if not already done.
• Communicate to Sri Lankan customers that invoices from April 1 include 18% VAT.
• Confirm VAT ID registration to ensure customers can claim input tax credits on their returns.

May 2026 — New Announcements

These are the announcements published directly by Partner Center for May 2026. Short but significant — particularly the M365 E7 general availability and the price list corrections that every partner pricing team needs to action.

Microsoft 365 E7 & Agent 365 — Now Generally Available

Date: May 1, 2026. Microsoft has officially launched Microsoft 365 E7, the Frontier Suite powered by Work IQ. It brings together Microsoft 365 E5, Copilot, Agent 365, and the Microsoft Entra Suite into a single integrated licence — the most comprehensive productivity and security bundle Microsoft has ever offered.

The Control Plane for Agentic AI

Agent 365 is the platform layer that lets organisations observe, govern, and secure both Microsoft and third-party AI agents. It is grounded in Work IQ shared intelligence and built with enterprise trust and compliance at its core. This is what differentiates E7 from E5+Copilot — the ability to manage and orchestrate AI agents at scale, not just use them.

⚡ Sales Motion — Start Now

• Read the official GA blog at aka.ms/microsoft-365-e7-general-availability for full product details and customer positioning language.
• Download seller readiness materials and partner enablement resources from the CSP partner page.
• Map your E5 customer base — every E5 customer is an E7 upsell opportunity.
• Enrol in Copilot + Power Accelerate if not already — Agent 365 is now an eligible workload for Immersion Briefings, Envisioning sessions, PoCs, and Deployment Accelerators.
• Verify promo availability in Partner Center before quoting (slight delay possible post-May 1).

New Commerce License-Based Price Lists — May 2 Correction

Date: May 2, 2026. The May 1 new commerce license-based price lists were published with two errors: incorrect effective end date values of 5/4/2026 (instead of the correct month-end date), and missing SKU line items in the Extended Service Term (EST) price lists. Both issues have been corrected in updated price list files published on May 2.

⚡ Pricing Team Action

• Go to the Pricing workspace in Partner Center and download the latest price list files (verify the last updated date shows 5/2/2026).
• Discard or replace any May 1 price list downloads with the corrected May 2 versions.
• Confirm your automated pricing systems or billing platforms have ingested the corrected data.
• Check EST-specific price lists — these had missing SKU lines that are now restored.

10 Important Questions Microsoft CSPs Should Be Asking

We downloaded the May price lists on May 1. Do we need to download them again?

Yes. The May 1 price lists contained errors — incorrect effective end dates and missing EST SKU lines. Corrected versions were published on May 2. Check the "last updated" date on your files: it should show 5/2/2026. If it shows 5/1/2026, replace your files immediately. No actual prices changed — this is a data correction, but the wrong end dates could cause issues in downstream billing or quoting tools.

What exactly is Microsoft 365 E7, and how do I position it versus M365 E5?

M365 E7 is E5 + Copilot + Microsoft Entra Suite + Agent 365, all in a single integrated licence, built on Work IQ shared intelligence. The positioning difference is substantial: E5 is enterprise security and productivity; E7 is the agentic operations platform — designed for organisations ready to deploy and govern AI agents at scale. Your buyer conversation shifts from IT administrators to CISOs, AI leads, and digital transformation executives. Launch promotions of 10–15% off are available through December 31, 2026.

What is Agent 365, and who in my customer base needs it?

Agent 365 is the control plane for AI agent management — it allows organisations to observe, govern, and secure both Microsoft-native and third-party AI agents. It's grounded in Work IQ and built for enterprise trust. Target customers are organisations that have already adopted Copilot and are now looking to move beyond individual AI tools to orchestrated, governed agentic workflows. If your customers are asking "how do we manage all these AI tools?" — Agent 365 is the answer.

Our Dragon Copilot customers are healthcare providers. What do we need to do before May 1?

Act before May 1, 2026 on two fronts: (1) The Physician Practice SKU reaches end of sale on May 1 — customers on this SKU need to transition to the standard per-user licence at the new reduced price. (2) Update your customer-facing materials and internal quoting tools to reflect the new lower price point and the simplified per-encounter consumption model. Contact your Microsoft account representative for updated Dragon Copilot Partner Assets (available May 1).

How does License Mobility for Windows Server/SQL Server subscriptions change our migration conversations?

It removes a major objection. Previously, customers moving from legacy Volume Licensing to CSP subscriptions under the new commerce experience would lose License Mobility rights (the ability to run workloads in shared or outsourced environments). That's now resolved as of April 1. Update your sales scripts — this is a concrete new benefit for CSP subscriptions. Note: perpetual licences are not affected; this benefit is for subscriptions only.

My Tax ID details are already in Partner Center. Why do I still need to review them?

Because the Tax ID system itself has changed. Microsoft's Global Tax ID modernisation (April 1–13 rollout) introduced country/region-specific Tax ID types that dynamically adjust to local requirements. What was sufficient before may not populate the new mandatory fields — particularly in Brazil, India, Italy, Egypt, and Serbia, where multiple Tax IDs may now be required by law. Log in to Partner Center and review your Tax ID entries in the updated interface. Don't assume existing data is complete under the new system.

Our billing system still treats ReferenceId as a plain string in reconciliation files. Is it too late to fix this?

The April 15 deadline has passed, so the JSON format change is already live. If you haven't updated your parsing logic, your reconciliation pipeline is producing errors or incorrect data right now. Prioritise this fix immediately. The ReferenceId field now returns a structured JSON object with both an identifier and a version field — any code expecting a simple string will fail to parse it correctly. Test against current Partner Center reconciliation files once the fix is deployed.

How do we prepare customers for the July 1 Microsoft 365 price increase?

Start renewal conversations immediately. Customers who renew before July 1 lock in current pricing. Use Microsoft CloudAscent to identify accounts with near-term renewal dates and prioritise outreach to high-value, multi-seat customers. Frame the conversation around the expanded value being delivered in M365 (Copilot Chat integration, Defender enhancements, endpoint management improvements) — and pair it with a discussion of E7 as a natural upgrade path for E5 customers.

What is the Extended Service Term (EST), and which of my customers are at risk of being moved into it?

EST is a month-to-month continuation mode that activates when a subscription expires without being renewed or cancelled. Billing is at the standard monthly rate with a 3% uplift. From May 4, 2026, subscriptions automatically enter EST if they meet all three conditions: purchased on or after April 1 2025; expiring on or after April 1 2026; and auto-renew is set to off. Use the EST download feature in Partner Center to export your full list of eligible subscriptions and act before they expire.

What promotions are currently active that we should be prioritising in Q2 2026 customer conversations?

The highest-priority promotions for May 2026 are: M365 E7 at 10–15% off (new, available through Dec 31 2026); Microsoft Sentinel 50GB at up to 32% off PAYG (available through June 30 2026); M365 E5 at 15% off for new customers (through June 30); and M365 Copilot at 30% off for eligible customers purchasing 300+ annual licences. Build these into your Q2 pipeline planning and customer business reviews now.

Detailed Breakdown & Key Actions Required

Here is the operational playbook for each major announcement. Use this section to brief your specific teams — billing, ops, security, sales, and programme management — on exactly what they need to do and when.

Microsoft 365 E7 & Agent 365 — Upsell Execution

M365 E7 is now live and transactable. The window to establish early momentum with E7 pipeline is open — partners who move fast will lock in customers at promotional pricing and establish the agentic AI narrative ahead of competitors.

• Segment your customer base by current M365 tier: E3 customers are E5 upgrade conversations; E5 customers are E7 upgrade conversations.
• Map Copilot adoption among E5 customers — those who have adopted Copilot but not formally governed it are your strongest E7 prospects (Agent 365 solves their governance problem).
• Download the E7 launch kit from aka.ms/ME7LaunchKit — includes partner FAQ, customer pitch materials, and sales guidance deck.
• Read the official GA blog at aka.ms/microsoft-365-e7-general-availability for detailed product content and positioning language.
• Brief your pre-sales and solutions team on the Entra Suite and Agent 365 components — these differentiate E7 from a simple Copilot add-on.
• Enrol in Copilot + Power Accelerate if not already active — Agent 365 qualifies for Immersion Briefings, Envisioning sessions, PoCs, and Deployment Accelerators.
• Set up demo environments and internal sandbox access for E7 before customer calls.
• Confirm promotion availability in Partner Center before quoting — a slight delay in promo transactability may apply post-May 1.

Dragon Copilot — Pricing & SKU Migration

The Physician Practice SKU is end-of-sale on May 1. The reduced per-user list price and new per-encounter consumption model open new adoption conversations across healthcare organisations.

• Pull a report of all Dragon Copilot Physician Practice SKU customers — these need transitioning to the standard per-user licence at the new price point before or at their next renewal.
• Update all Dragon Copilot entries in your quoting tools, PSA systems, and customer-facing rate cards to reflect the new reduced price.
• Prepare customer communications explaining the SKU consolidation and that the new per-user licence includes all enterprise capabilities at a lower price.
• Rebuild any ROI calculators or cost models using the new per-encounter consumption billing model instead of per-note or per-action.
• Access updated Dragon Copilot Partner Assets from partner.microsoft.com/asset/collection/dragon-copilot-partner-assets on May 1.
• Contact your Microsoft account representative for specific guidance on geography-specific pricing details.

Windows Server & SQL Server License Mobility — Update Your Sales Motion

License Mobility rights are now automatic for CSP subscription customers under MCA. This changes the migration conversation for any customer still on legacy VL agreements for server workloads.

• Update all Windows Server and SQL Server sales scripts and customer-facing materials to reflect the new License Mobility benefit.
• Clearly distinguish subscription (License Mobility included) from perpetual licences (no change) in all partner and customer communications.
• Review the updated product terms on microsoft.com/licensing and the partner FAQ (available via Microsoft partner resources).
• Re-identify customers currently on traditional VL agreements who have cited License Mobility as a barrier — the objection is now removed.
• Update your Azure migration pitch decks and hybrid deployment guides to reference the updated product terms.
• Train your pre-sales team on the correct distinction to avoid inaccurate commitments to customers regarding perpetual licences.

Global Tax ID Modernisation — Partner Center Verification

Microsoft has overhauled Tax ID collection across all regions. Partners in key jurisdictions must verify and potentially add multiple Tax IDs to avoid billing disruptions.

• Log in to Partner Center and navigate to the appropriate Tax ID section for your programme (MAICPP: Billing Profile; CSP Direct/Indirect: Legal Info → Bill to Info).
• Review all existing Tax ID entries under the new dynamic country/region-specific interface.
• Partners in Brazil, India, Italy, Egypt, and Serbia: look for newly displayed mandatory Tax ID fields and fill them in.
• Confirm all mandatory Tax ID fields show as complete — incomplete fields are flagged clearly in the new interface.
• For tax treatment questions, engage your tax advisor or local tax authority, not Microsoft support.
• Submit a support ticket via Partner Center (not by phone) for operational or navigation questions about the new Tax ID interface.

May Price List Corrections — Verify You Have the Right Files

The May 1 price lists contained data errors. Corrected versions are available as of May 2. Pricing teams must verify their systems are using the corrected data.

• Navigate to the Pricing workspace in Partner Center and check the "last updated" date on your new commerce license-based price list files — should read 5/2/2026.
• If your files show 5/1/2026, download the corrected versions immediately and replace them in any billing or quoting systems.
• Check the EST price lists specifically — these had missing SKU line items that are now restored in the May 2 versions.
• For automated systems that pull price list data on a schedule, confirm the latest pull occurred after 5/2/2026 and ingested the corrected data.
• Validate any quotes issued on May 1 that referenced EST pricing — they may have used incorrect end dates or missed applicable SKUs.

Extended Service Terms & July Price Increase — Proactive Renewal Strategy

Two imminent events demand proactive renewal action: EST full enforcement on May 4, and the global M365 price increase on July 1. Both reward partners who act early.

• Download the EST subscription report from Partner Center — identify every subscription with auto-renew off that was purchased after April 1 2025 and expires after April 1 2026.
• Contact each EST-eligible customer before May 4 — confirm renewal preference or cancel proactively to prevent unwanted EST billing at the monthly rate + 3% uplift.
• Run a renewal report in CloudAscent to identify M365 customers with renewals coming up before July 1 2026.
• Prioritise outreach to high-seat-count customers and multi-product accounts where the July price increase will have the greatest financial impact.
• Use the renewal conversation to introduce E7 as an upgrade path — pair the price increase with a value discussion about what's included in E5 and what E7 adds.
• For customers not ready to upgrade, at minimum secure a renewal before July 1 to lock in current pricing.
