Microsoft is investigating a strange bug in classic Outlook that makes your mouse cursor disappear while you are using the app.
When this happens, the pointer is not visible, but emails still react as if you are hovering over them. They change color as you move the mouse. The issue has also been seen in other Microsoft 365 apps like OneNote, but Outlook seems to be hit the most.
Microsoft says it is looking into the problem and is asking IT admins to submit support cases with WebView2 logs.
For now, the workarounds are not ideal. You can try clicking an email, switching to PowerPoint and back, or restarting your PC. There is no timeline yet for a proper fix.
