Latest Message<\/th>\nTitle: Users may be unable to install Microsoft 365 desktop apps on Windows devices<\/p>\n

User impact: Users may be unable to install Microsoft 365 desktop apps on Windows devices.<\/p>\n

More info: This only impacts users who attempt to install version 2508 (Build 19127.20358) and version 2507 (Build 19029.20294) of the Microsoft 365 desktop apps.<\/p>\n

Current status: We’re continuing to develop a set of two builds that address the authentication component misconfigurations, with the build for version 2508 validated and in the process of deploying. We anticipate that our second build for version 2507 will be ready for final validation by our next scheduled update, after which we’ll deploy to fully remediate impact.<\/p>\n

Scope of impact: Any user attempting to install Microsoft 365 desktop apps on Windows devices may be impacted.<\/p>\n

Start time: Tuesday, November 11, 2025, at 6:00 PM UTC<\/p>\n

Root cause: A newly released set of authentication components contain a misconfiguration that prevents users from installing Microsoft 365 desktop apps on Windows devices.<\/p>\n
