Title: Users may be unable to join shared channels using some links to messages in Microsoft Teams User impact: Users may be unable to join shared channels using some links to messages in Microsoft Teams. More info: This issue specifically affects links generated using the “Copy Link” option through the three dots menu located at the top right of the shared channel. Users can bypass this impact by generating links to channels using any alternate method, such as by right-clicking on the channel in the left rail menu or any specific message within the shared channel and choosing the “Copy Link” option there. Current status: The fix is continuing to deploy successfully, and affected users may begin experiencing recovery as deployment progresses. We expect the deployment to be fully completed by the end of the week of September 4, 2026. Scope of impact: Users joining channels or generating channels links using the “Copy Link” options within the three dots menu located at the top right of shared Microsoft Teams channels may be impacted. Root cause: A recent update intended to improve the data pathways leveraged to facilitate channel link generation is causing the affected links to be malformed, leading to impact.
