Outlook Scan PST

If you can't open your Personal Folders file (.pst) or your Offline Folder file (.ost), or you suspect that your .pst or .ost data file is corrupted, you can use the Inbox Repair tool (Scanpst.exe) to diagnose and repair errors in the file. The tool determines whether the file structure is intact. If it is not intact, the Inbox Repair tool resets your file structure and rebuilds the headers.

Step-by-step guide

1. Exit Outlook if it is running.
2. Double-click Scanpst.exe, located at C:\Program Files (x86)\Microsoft Office\OFFICE(number).
3. If the "Enter the name of the file you want to scan" box is empty, click Browse and navigate to C:\Users\[yourusername]\AppData\Local\Microsoft\Outlook\ and select the appropriate email address
4. Click Start.
5. If errors are found after the scan is complete, you will be prompted to start the repair process to fix the errors.
6. A backup file is created during the repair process. To change the default name or location of this backup file, in the "Enter name of backup file" box, enter a new name, or click Browse to look for the file that you want to use.
7. Click Repair.
8. Once the repair is finished, open Outlook and determine if the problem was solved.
   1. If not, consider doing an Office Repair
