Copilot Credits Guide – September 2026

Microsoft have updated the Copilot Credits Guide (four times!) for September 2026.

App building is the focus this month, with a key update covering Apps in Copilot Cowork, a feature that’s part of the early-access Microsoft Frontier Program. The guide covers details of App creation using natural language, billing, and hosting, and includes a useful illustration of its estimated Copilot Credits usage. The third update of the month adds a new section on Apps in Microsoft Copilot Studio, a feature in Paid Public Preview, covering usage-based billing for building, hosting, running, and managing Apps, its inclusion in the Power Apps Premium licence, and cost estimation. The fourth version features an updated term for the Microsoft-hosted cloud infrastructure, renaming “Microsoft-managed host” to “Copilot Managed Runtime Host”, along with an added section providing further details.

A flurry of other changes includes added terms, prerequisites, and useful links throughout.

Don’t forget the “What’s New” feature in our Licensing Guides Gallery, where we provide an overview of all the important changes. Subscribers can find all versions of the PDF guide here: https://bit.ly/4xPrgVI, alongside the ever-popular Cautionary Notes to navigate the errors we’ve discovered.

Apps in Copilot Studio and Copilot Cowork

Microsoft announce App building in Copilot Studio and Copilot Cowork, alongside the existing options of Agents and Workflows.

With rollout starting in September, users in the early-access Frontier Program can use natural language to create, edit, and publish Apps that optionally use organisational data. It’s all enabled by the GitHub Copilot Harness and that means that both the building of the Apps and running them consumes Copilot Credits. As you’d hope, admins can manage the App policies and stats in the Microsoft 365 Admin Center.

Windows 10 LTSC 2021 ESUs

Extended Security Updates (ESUs) are now available for Windows 10 Enterprise LTSC 2021, ahead of its End of Support date on 12 January 2027.

The ESUs cover eligible devices for three years post-support, until 8 January 2030, and you can purchase them through CSP or Volume Licensing. Following the usual rules, pricing doubles each year, although you can take advantage of a cheaper licence if you manage the devices with Intune or Windows Autopatch.

Exchange Server and Skype for Business Server End of Support

Microsoft confirm the paid End of Support date for Exchange Server 2016/2019 and Skype for Business Server 2015/2019 as the end of October 2026.

The original deadline of 14 October 2025 was extended with a double dose of ESUs ultimately lasting for an additional 12 months. Microsoft have reiterated that this phase of support is final, recommending (unsurprisingly!) upgrading any installations of Exchange Server and Skype for Business Server to a supported version. Subscribers will find the full details explained across LicenseVerse.

Retirement of Publisher

Publisher will no longer be supported from October 2026.

As of 1 October 2026, subscribers with a Microsoft 365 licence will no longer have access to Publisher, and it won’t be included with new purchases. You can still use the application beyond October if you have a perpetual licence for Office LTSC 2021 (the last version to include it), but support ends on 13 October 2026. Microsoft recommend migrating to Word or PowerPoint as alternatives.
