Microsoft Reference: TM1448287

Issue Status: ONGOING

Issue Description: Users may be unable to close the share tray when using the “Share window” feature in Microsoft Teams Town Halls.

More info: While we work towards full remediation, impacted users may do any of the following as a temporary alternative:

-Stop window sharing, click “Back” on the share tray, then resume sharing
– Leave the Town Hall and rejoin
– Use the “share screen” feature instead of the “share window” feature, which will not display the share tray.

Current Update: 06/08/2026 08:31:00 AM – Microsoft successfully developed and initiated the deployment of a code change fix to resolve impact. They will monitor the deployment of this fix and share a timeline for completion once one becomes available

Scope of impact: Any user who uses the “share window” feature in Microsoft Teams Town Halls may be affected and may be unable to close the share tray feature while window sharing. This section may be updated as our investigation continues.

Root cause: A recent deployment of a feature change introduced a code conflict, which resulted in users being unable to close the share tray when using the “share window” feature in Microsoft Teams Town Halls.
