The Microsoft Teams desktop client has encountered a notable bug affecting users on both macOS and Windows platforms following the recent update to build 26072.519.4556.7438. The primary concern revolves around the right-click functionality, which has ceased to operate effectively within the application. Consequently, users are advised to resort to keyboard shortcuts for clipboard operations, specifically Ctrl+C, Ctrl+X, and Ctrl+V.
First mentions on the Patchmanagement.org mailing list
The initial mention of this issue surfaced last Friday on the Patchmanagement.org mailing list, in a post titled “Users may be unable to use the copy and paste function in Microsoft Teams desktop client chats.” This discussion referenced issue TM1279908, which highlighted a service degradation alert from Microsoft 365 regarding the Microsoft Teams platform. Users have reported difficulties in copying and pasting URLs, text, and images within chats, as the paste option appears grayed out when attempting to access it through the context menu.
In response to these challenges, Microsoft has suggested a workaround: users can manually copy the desired content using Ctrl + C (or Cmd + C on Mac) and paste it with Ctrl + V (or Cmd + V on Mac). In a recent status update, Microsoft acknowledged that it has pinpointed the potential root cause of the issue.
Furthermore, the company is currently implementing a phased rollout of a fix while actively monitoring telemetry data to ensure the resolution is effective. The next status update is anticipated on April 21, 2026. For those seeking additional insights, further details can be found in a related blog post available in German, which can be translated using built-in tools.
