How to repair Microsoft Outlook .pst and .ost data files

Question

Ich hatte bisher Outlook 2007. Jetzt Microsoft Office 2021 Home & Business installiert. Beim Öffnen von Outlook kommt die Fehlermeldung:

Microsoft Outlook kann nicht gestartet werden. Das Outlook-Fenster kann nicht geöffnet werden. Diese Ordnergruppe kann nicht geöffnet werden. Fehler in der Datei.

C:\Users\fuchs\AppData\Local\Microsoft\Outlook\Outlook.pst

Ich weiss nicht mehr, was ursprünglich in diesem Ordner war. Ich habe da das Backup eingefügt, wieder gelöscht, alles in diesem Ordner gelöscht usw.

Was stimmt da nicht?

Hello Hans,

Thank you for posting in Microsoft Community.

It seems like there might be an issue with your Outlook data files (.pst and .ost). To repair these files, you can use the built-in Inbox Repair tool (scanpst.exe) that comes with Microsoft Outlook. Here are the steps to use the Inbox Repair tool:

1. Close Outlook.
2. Open the Windows File Explorer and navigate to the following location: C:\Program Files (x86)\Microsoft Office\root\OfficeXX (where XX is the version number of your Office installation).
3. Find the scanpst.exe file and double-click it to open the Inbox Repair tool.
4. In the Inbox Repair tool, click the Browse button and navigate to the location of your Outlook data file (Outlook.pst).
5. Select the file and click the Start button to begin the repair process.
6. Once the repair process is complete, open Outlook and see if the issue has been resolved.

If the issue persists, you may need to create a new Outlook profile: Übersicht über Outlook-E-Mail-Profile - Microsoft-Support
