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

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

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

Final status: We\u2019ve confirmed that the fixed build is fully deployed and available and we\u2019ve determined that users are now able to install Microsoft 365 desktop apps on Windows devices as expected. <\/p>\n

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

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

End time: Tuesday, November 18, 2025, at 9:00 PM UTC<\/p>\n

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

Next steps:
– We\u2019re reviewing our validation and updating procedures to better detect and prevent issues like this prior to deployment in the future. <\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
