If Outlook keeps crashing or refuses to open, try running it in Safe Mode.
Press Win + R, type outlook.exe /safe, and hit Enter. If it opens fine, one of your add-ins is likely causing the crash — disable them one by one from File → Options → Add-ins.
You can also repair Office from Control Panel → Programs → Microsoft 365 → Change → Quick Repair.
If that doesn’t help, create a new Outlook profile under Mail (Control Panel). Corrupt data files often lead to startup crashes.
