Description¶
This error indicates that the PST isn't able to be accessed by BackupAssist.
Resolution¶
- Check that the PST file isn't currently in use by another program (such as Outlook).
- Check that any security software installed on the system isn't currently scanning the PST file.
Make sure that your Backup User Identity has sufficient permissions to be able to access the PST file.
Check that your Backup User Identity has been set and has the required access. To view your current Backup User Identity, select the Settings tab > Backup User Identity and you'll see the following dialogue box appear.

Note
For BackupAssist 10.4.2 and earlier, the Backup User Identity is used for all backup jobs and the account may have been created with custom access levels. For 10.4.3 and later, a Backup User Identity is only required for Jobs that have a NAS destination or the SQL add-on, and in these cases, the Backup User Identity should be a member of the Administrators group.
What to check¶
- For BackupAssist 10.4.2 or earlier - check that the account is still selected, enabled and has the required access.
- For BackupAssist 10.4.3 and later, check that the account is still selected, enabled and a member of the administrators group.
- To check the permissions properly, you can log into the backup server using the Backup User Identity account and check that you can read and write to the backup destination without any authentication requests or errors.
- If backup account's password is changed in Windows, it will need to be changed in BackupAssist.
