Please be aware that this forum is made up of fellow users and volunteers. Microsoft does not provide direct support here, as it is intended as a space for users to assist one another. That said, you could open Outlook in safe mode to check if it is caused by an add-in. Close Outlook in Task Manager, then press Win + R then enter outlook.exe /safe. If the problem disappears in safe mode, relaunch Outlook normally, then try to turn off all add-ins and re-enable them one at a time to find the culprit.
