Cannot Start Outlook: ".pst is in use"
This is a message that popped up this morning, when I opened oulook. Fixt it:
- Your .pst file is corrupted.
- Your .pst file is in use by another program.
1 - Your .pst file is corrupted.
There are plenty of good guides on how to repair your .pst file:
This can also help if outlook fails to index.
2 - Your .pst file is in use by another program.
After a few years of use a .pst file can become very large. Mine is currently at 9.0GB. This means that a backup / sync programs such as syncbac, can take several minutes to backup / sync the .pst file.
During this time you will receive the error message ".pst file in use", if you open outlook.
