Microsoft TeamsCustom Summary Feature Re-Enablement Timeline

Rogerson, Nick 20

I have noticed that the Custom Summary Tool has been disabled by Microsoft. I manage a key business program that utilizes this tool daily. When should we expect to see the tool re-enabled? This timeline will help guide our response. Thank you.

Hi @Rogerson, Nick,

I hope you’re having a great day.

Thank you for reaching out and for sharing the details.

I’d like to confirm that this behavior aligns with an active Microsoft Teams service advisory: TM1290947 (“Users may be unable to use the Custom AI meeting summary feature for Microsoft Teams due to the feature being disabled”).

Microsoft has identified that a recent code change impacted the feature and is actively working on remediation. According to the latest Service Health update, Microsoft has developed and validated a fix, and they are expected to share an updated deployment timeline in their upcoming Service Health communication.

If you are part of an organization, your IT admin can monitor the status directly through Microsoft 365 Admin Center > Health > Service Health, where Microsoft posts active updates about the advisory. Your IT admin can also open a support request with Microsoft for tenant-specific assistance and updates.

I sincerely apologize for any inconvenience this may have caused, especially given how critical this tool is to your daily operations. I kindly ask for your understanding while Microsoft continues working on the fix.

Hi @Rogerson, Nick,

Thank you so much for following up.

I checked the latest update for Microsoft Teams service advisory TM1290947 in Service Health. As of the most recent posted update (Apr 29, 2026, 11:13 PM GMT+7), Microsoft has not yet provided a confirmed re-enablement / resolution timeline. The update states that Microsoft is continuing to monitor the propagation of the code change across the affected infrastructure, and that once available, they will provide a resolution timeline. Microsoft also notes the next scheduled update is by Friday, May 1, 2026 at 8:00 PM GMT+7.

For the most timely visibility, please ask your organization’s IT admin to monitor this directly in Microsoft 365 Admin Center > Health > Service Health, where Microsoft posts the active updates as they become available. Your IT admin may also choose to open a support request with Microsoft for tenant-specific assistance and to receive direct communication related to your environment.

As a community moderator, I only have access to the information published in Service Health and do not have additional internal details beyond those advisories. That said, as soon as Microsoft posts any new guidance or a firm timeline, I will be happy to share it with you immediately.

I sincerely apologize for the continued disruption, especially given how critical this feature is to your daily operations, and I appreciate your patience and understanding while Microsoft works toward full restoration.
