The Microsoft Teams desktop client has a bug affecting users on macOS and Windows after the update to build 26072.519.4556.7438, specifically with the right-click functionality not working. Users are advised to use keyboard shortcuts (Ctrl+C, Ctrl+X, Ctrl+V) for clipboard operations. The issue was first mentioned on the Patchmanagement.org mailing list, referencing issue TM1279908, which noted service degradation alerts from Microsoft 365. Users have reported problems with copying and pasting URLs, text, and images, with the paste option grayed out in the context menu. Microsoft has identified a potential root cause and is rolling out a fix while monitoring telemetry data, with the next status update expected on April 21, 2026.
