ISSUE
Multiple customers have reported issues with Office features that rely on WebView2, notably Copilot, Share, and Room Finder. The most impactful symptom is the failure of the Copilot pane to launch when multiple Office applications are open simultaneously.
If there are error messages, best practice is to insert a screenshot image.
This occurs when one Office application (e.g., Excel) has already initiated a WebView2 instance, and another (e.g., OneNote) attempts to start a second instance. If the first application is closed, the Copilot pane in the second application opens successfully.
STATUS: INVESTIGATING
The Office team is working on the issue and will update this article when a fix is released.
