Microsoft Reference: TM1286858

Issue Status: RESOLVED

Issue Description: Users may experience intermittent failures or delays when starting recording features in Microsoft Teams meetings.

More info: Impacted users may notice that after selecting the option to start recording, transcription, or closed captions, the action takes longer than expected to begin or may fail. In some cases, retrying the action may succeed after a delay. Stopping recordings doesn’t appear to be impacted and continues to work as expected.

Final Update: 22/04/2026 08:18:00 AM– Microsoft has confirmed through internal service monitoring that our service scaling optimization changes together with their rollback of the impacted build have successfully resolved the issue, remediating impact.

Scope of impact: Impact is specific to some users on Microsoft Teams build 26040401710 attempting to start recording, transcription, or closed captions in Microsoft Teams meetings. This information may be updated as our investigation continues.

Root cause: A recent client update to Microsoft Teams build 26040401710 introduced unintended behavior within the Teams client, causing recording-related components to trigger incorrectly during meeting setup. This increased service traffic on these components, resulting in impact.

Next steps: Microsoft are reviewing our update testing and validation methods to better identify potential issues such as this prior to deployment to prevent similar impact in the future.
