Using Classic Outlook on Windows for personal email, calendar, and contact management
Sorry to hear that Classic Outlook will not open. Could you clarify what happens when you try—does nothing appear, does it remain at “Loading Profile,” or do you receive an error message? Please share a screenshot of any error and confirm your Office version and whether the repair you performed was Quick Repair or Online Repair.
Try to open Task Manager and end any Microsoft Outlook or Office processes. Then press Windows + R, enter:
outlook.exe /safe
If Outlook opens in Safe Mode, an add-in is probably causing the issue. I’ll be waiting for the results and the requested information to continue helping you.
