Latest Message<\/th>\nTitle: Some users with an active Microsoft Teams license may be unable to sign in to Microsoft Teams <\/p>\n

User impact: Users with an active Microsoft Teams license may have been unable to sign in to Microsoft Teams. <\/p>\n

More info: Additionally, admins may have been unable to access organization wide settings. <\/p>\n

Final status: We\u2019ve completed the reversion of the offending authorization configuration change and confirmed through service telemetry that the issue is resolved. <\/p>\n

Scope of impact: Impact was limited to some users with an active Microsoft Teams license who attempted to sign in to Microsoft Teams. <\/p>\n

Start time: Thursday, August 27, 2026, at 2:41 PM UTC <\/p>\n

End time: Thursday, August 27, 2026, at 9:58 PM UTC <\/p>\n

Root cause: A recent authorization configuration change intended to block users without active licenses inadvertently blocked some users with active Microsoft Teams licenses, resulting in impact. <\/p>\n

Next steps: We’re 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
