Issue Status: RESOLVED

Issue Description: Users may be unable to create meetings from their new calendar in Microsoft Teams.

More info: Impact is specific to some users who have set a meeting policy where copilot is disabled and meeting recording is set to ‘On’, which populates the following error message:

”Couldn’t create a Teams meeting. Send the invite to reserve the time and try making it a Teams meeting later.”

Final Update: 05/09/2025 08:40:00 AM – Microsoft identified that their previously-identified root cause, where impact appeared to be specific to users with policies disabling Microsoft Copilot, may not have been the singular underlying source of impact. After further analysis, we determined that a portion of regional infrastructure leveraged to facilitate meeting creation entered an unhealthy state but has since recovered. They’ve confirmed through user feedback and additional testing that impact is fully resolved.

Scope of impact: Some users who are attempting to create meetings from their new calendar in Microsoft Teams who have set a meeting policy where copilot is disabled, and meeting recording is set to ‘On’, may be impacted.

Root cause: Copilot Mode is disabled while the ”Recorder Option” is set to ”Organizers And Presenters Only”, which isn’t supported by their meeting scheduling service, resulting in impact.

Next steps: Microsoft are continuing to monitor the affected infrastructure closely to gain further insight into the source of the underlying issue and identify ways to better prevent similar impact in the future.
