We are announcing Service Principle Name (SPN) filtering for application users in Power Platform. This enhancement allows administrators to configure IP firewall settings to bypass or restrict access for specific third-party application users. Previously, IP firewall settings applied to all application users but now, admins can target access more precisely.
We’ve released updates to the following update channel for Microsoft 365 Apps:
Microsoft is retiring the Team Guidance feature in Microsoft Places by November 3, 2025, to streamline collaboration and promote Microsoft 365 Groups. The retirement includes phased read-only and removal stages. Organizations should inform users, transition to Microsoft 365 Groups, and update training accordingly.
A new Copilot Search usage report will be available in the Microsoft 365 admin center by early September 2025, showing user activity and search metrics. It is enabled by default, requires no setup, and helps organizations monitor Copilot Search adoption and usage trends.
The rollout of line key configuration in Teams Admin Center for Teams phones is paused worldwide to address feedback and improve shared device license support. Admins should configure line keys directly on devices temporarily. Audit logging and reporting via TAC may be affected until the experience resumes.
Microsoft Defender Core service will be introduced for Windows Server 2012 R2 and 2016 to improve Defender Antivirus stability and performance. Public preview starts August 28, 2025; general availability by early October 2025. It installs by default with platform update 4.18.25060.7-0 and requires specific URL allowances and process whitelisting.
The Microsoft Intune In Development page for September 2025 has been updated with upcoming features. Organizations should review the changes to prepare IT staff and update user guidance accordingly, as these features will appear in the next month or later releases.
We are announcing the ability for admins to enforce the use of end-user credentials by managing how authentication is handled. This feature will be generally available starting September 19, 2025.
I've been working with Microsoft Technologies over the last ten years, mainly focused on creating collaboration and productivity solutions that drive the adoption of Microsoft Modern Workplace.
