How can I repair “Outlook automatically closes after opening” error?

Outlook closes automatically after opening is often due to a corrupt add-in or damaged PST file. Try starting Outlook in Safe Mode (Press Windows + R, type outlook /safe, and hit Enter). If Outlook opens without any issue, then you should disable all faulty add-ins. Next, to repair the PST files—use the ScanPST tool or try Yota PST Converter, which repairs corrupted PST files effectively without data loss. Updating Outlook and creating a new profile are also good solutions. Try these steps and you’ll fix the problem very easily.
