Microsoft Product Highlights and Updates
Unified Microsoft Copilot app — new URL, broad rollout mid-September
From August 18, 2026, Microsoft began updating the Copilot web, desktop, and mobile experiences to help users distinguish work from personal accounts — clearer account indicators, a simplified app name and icon, and a move of the web app URL from m365.cloud.microsoft to copilot.cloud.microsoft, with automatic redirection unless the new URL is blocked. An early preview of the Windows and Mac desktop experience landed August 18, with broad deployment beginning mid-September. Action for customers: confirm copilot.cloud.microsoft isn't blocked by network, proxy, firewall, or access policies, and add *.cloud.microsoft to allow lists.

Build apps by prompt in Copilot Cowork (September 10)
Microsoft announced full-stack business app building through conversation in Copilot Cowork and Copilot Studio — described as creating full-stack business apps through conversation, grounded in your data. Users describe the app, Cowork generates a first version to refine and test, apps connect to org data through approved connectors under existing governance, and admins will be able to publish finished apps org-wide via the Microsoft 365 admin center. The experience is in preview for Frontier program customers with an eligible Microsoft 365 Copilot license. Schedule time with your Account Manager to review.
Microsoft Price Updates
5% cost-of-capital uplift on monthly-billed annual CSP software — effective October 1, 2026
Starting October 1, 2026, Microsoft applies a 5% cost of capital uplift for CSP software subscriptions (such as SQL Server, Windows Server, Client Access Licenses, and System Center) with annual-term commitments billed monthly, aligning pricing treatment across sales channels while preserving monthly billing flexibility. There is no change to annual billing or month-to-month subscriptions, and for existing annual-term subscriptions billed monthly the uplift takes effect at renewal on or after October 1, 2026. Note that an earlier Microsoft communication carried an incorrect effective date — October 1, 2026 is the confirmed one. No Partner Center or system changes are required, but any customer renewing on or after that date should hear it from you first. Schedule time with your Account Manager to review.
Growth margins arrive October 1 — new economics on M365 growth
From October 1, 2026, growth margins give eligible partners incremental margin on qualifying Microsoft 365 growth opportunities, built on partner feedback to allow more flexibility to structure deals, compete for new business, reward reseller performance, and reinvest in capabilities. Technical guidance is available for the related API changes affecting data export and billing automation. Pair this in the newsletter with a reminder that the July 1, 2026 Microsoft 365 list price increases now hit customers at their first renewal on or after that date.

Microsoft Promos
The September 30 promo cliff — lock quotes in now
A large block of CSP offers stops accepting new transactions at the end of this month. The bundled offer of 10% and 15% discounts on Microsoft 365 E3 and E5 (three-year and one-year terms) plus 10% off the Defender Suite and Purview Suite — for new-to-E5/Defender/Purview customers, with no offer stacking — is available only through September 30, 2026. Microsoft 365 E7 and several Copilot term promos share the same deadline, and the deadline is the purchase date, not the subscription start. Practical guidance for readers: a quote built in Q1 and signed in Q2 loses the discount, so validate promotion IDs and eligibility in Partner Center at checkout. Schedule time with your Account Manager to review.
