Hi,
Please try granting yourself "Full Control" permission on the pst-file that is referenced and then check if the issue persists. To do this, please follow:
1. Browse to the PST file under User/Name/Documents\Outlook Files\
2. Right-click the PST file and select Properties.
3. Under Security tab, click Edit button.
4. Adjust the permissions for your name and make sure you have the "Full Control" permission.
5. Press OK. Click OK again.
6. Start Outlook and check if this issue is fixed.
Please let me know the result.
Regards,
