Latest Message<\/th>\nTitle: Some users may have been unable to schedule Microsoft Teams meetings through the classic Outlook desktop client<\/p>\n

User impact: Users may have been unable to schedule Microsoft Teams meetings through the classic Outlook desktop client.<\/p>\n

More info: Impact was specific to Microsoft Teams version 26149.1205.4798.6437. The Teams Meeting add-in appeared to have been installed and enabled in classic Outlook; however, it wasn’t being displayed, preventing affected users from scheduling Teams meetings directly from the Outlook ribbon.<\/p>\n

Final status: We’ve confirmed that the deployment has successfully completed and validated through service health telemetry that the issue has been resolved and impact no longer persists.<\/p>\n

Scope of impact: Users on Microsoft Teams version 26149.1205.4798.6437 and attempting to create and schedule Microsoft Teams meetings through the classic Outlook desktop client may have been impacted.<\/p>\n

Start time: Monday, June 22, 2026, at 1:16 AM UTC<\/p>\n

End time: Thursday, July 9, 2026, at 12:45 PM UTC<\/p>\n

Root cause: A recent service update introduced an incompatibility affecting how the Teams Meeting add-in identified the appropriate Teams client during initialization in newly configured Outlook environments impact, resulting in impact.<\/p>\n

Next steps: We’re reviewing our update procedures to better identify similar issues during our development and testing cycles.<\/p>\n

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