Affected services: Microsoft Teams
Status: Service degradation
Issue type: Advisory
Start time: Jun 4, 2024, 10:00 PM ADT

User impact
Users may be unable to perform multiple scenarios in Microsoft Teams.

More info
Affected users may be unable to perform the following scenarios in Microsoft Teams:
- Create a team from an existing group.
- Add a member to a team.
- Create a team or channel from a template.
- Duplicate a team.
- Archive and unarchive a team or channel.
- Share a channel with a team.
- Delete team will not delete all channels in a team.
- Newly created teams from Graph will not have members added.
- Clone a team.
- Restore channels in a team.
- Members won't be auto synced between groups and teams.

Additionally, updates may not be reflected in Microsoft Teams when user properties are updated in Microsoft Entra ID, and new teams created via Microsoft Graph may not have members added. Retries may be successful.

Scope of impact
This issue may impact some users performing one of the Microsoft Teams actions outlined in the More info section.

Root cause
An internal update affected a portion of infrastructure that processes various Microsoft Teams actions, such as the ones listed above in the "More info" section, which caused processing delays and a subsequent backlog.


Current status
Jun 14, 2024, 1:10 AM ADT
We're continuing to monitor and process the backlog of the older requests, which is taking longer than initially expected as we're working to ensure this action doesn't disturb the flow of new requests. In addition, our observation of the additional service pool we created to route all new requests is functioning within the expected timeframes.
Next update by:
Friday, June 14, 2024 at 2:00 PM ADT


History of updates

Jun 13, 2024, 10:21 PM ADT
The additional service pool to route all new requests has been created and the requests are being processed within the expected timeframes. We've deployed this pool to affected users and we're monitoring and working on processing the backlog of the older requests without disrupting the flow of new requests.

Jun 13, 2024, 8:11 PM ADT
We've created an additional service pool to route traffic to, which we expect will assist with processing these requests. We're testing this approach with a subset of active users to ensure that it will mitigate impact. This testing will also allow us to determine if the root of the problem is with the queues themselves or if the impact is originating from somewhere else.

Jun 13, 2024, 6:18 PM ADT
After reverting the previously healthy Microsoft Teams version, we've confirmed that the issue remains. While we have seen some improvement in performance, we're still seeing a growing backlog in our queues. We're implementing additional logging for visibility into why these queues remain stuck. In parallel, we're creating an additional service pool for processing these requests to route traffic to, in order to see if this mitigates the issue and determine if the problem is with the queues themselves or a deeper issue.

Jun 13, 2024, 1:57 PM ADT
We reverted the infrastructure update and implemented service optimizations for the affected infrastructure, but this didn't remediate impact as expected. We're reverting Microsoft Teams to a previous healthy version as a potential means of remediating impact. We expect this will complete by our next scheduled update.

Jun 12, 2024, 10:09 PM ADT
We've determined an internal update affected a portion of infrastructure that processes various Microsoft Teams actions, such as the ones listed above in the "More info" section, which caused processing delays and a subsequent backlog. We've reverted the update and performed optimization actions for the affected infrastructure to expedite processing the backlog of impacted Microsoft Teams actions. We're monitoring the processing's progress to ensure it finishes as expected, and we anticipate the impact will be resolved by our next scheduled communication.

Jun 12, 2024, 9:39 PM ADT
We're investigating a potential issue with Microsoft Teams and checking for impact to your organization. We'll provide an update within 30 minutes.

Title: Some users on the Teams classic client can't create Teams meetings through the Outlook desktop client

User impact: Users on the Teams classic client couldn't create Teams meetings through the Outlook desktop client.

More info: This event specifically impacted users who had the new Teams client installed on their device and uninstalled it in favor of the classic client. This would have also impacted users that had the latest version of new Teams installed, but then switched back to classic Teams without uninstalling. Additionally, this issue impacted meetings created using the Teams Meeting add-in. While this event was impacting, affected users could have switched to new Teams client then restarted their Outlook desktop client, and created meetings through the Teams calendar, or scheduled meetings through the Outlook web app to avoid the impact.

Final status: We've successfully deployed the fix that reverted the code that wasn't supporting the add-in on classic Teams and causing the impact. We've monitored service health telemetry and have validated that impact has been alleviated.

Scope of impact: This issue may have potentially affected some users on the Teams classic client that previously used the new client experience who were trying to create Teams meetings through the Outlook desktop client.

Start time: Monday, April 29, 2024, at 2:07 AM UTC
