Latest Message<\/th>\nTitle: Users may be unable to access tabs beyond the Conversation tab in certain Microsoft Teams channels <\/p>\n

User impact: Users may be unable to access tabs beyond the Conversation tab in certain Microsoft Teams channels. <\/p>\n

More info: Users may only see the Conversation tab in Microsoft Teams channels when channel names and associated sensitivity labels are long, particularly on smaller displays. As a result, other tabs such as Shared, Files, Notes, and custom tabs may not be visible.<\/p>\n

As a workaround, impacted users can zoom out in Teams, use a larger display where available, or, in some cases, select the overflow arrow to access hidden tabs. <\/p>\n

Current status: We\u2019ve determined that a recent configuration change associated with a user interface modernization effort inadvertently introduced a regression that is preventing Teams channel tabs from rendering correctly. We\u2019re deploying a fix to mitigate the impact and conducting internal validation to confirm it successfully resolves the issue. <\/p>\n

Scope of impact: Any user attempting to access tabs beyond the Conversation tab in Microsoft Teams channels with long channel names and\/or associated sensitivity labels may be impacted. <\/p>\n

Start time: Tuesday, August 18, 2026, at 1:30 PM UTC <\/p>\n

Root cause: A recent configuration change associated with a user interface modernization effort inadvertently introduced a regression that is preventing Teams channel tabs from rendering correctly. <\/p>\n
