When I try to delete any items in my personal folders, I get the following message: 'The messaging interface has returned an unknown error. If the problem persists, restart Outlook'. Restarting Outlook or reboot does not correct. I have also run the 'detect and repair' tool with no avail. Any suggestions. My personal folders are too full, and without deleting old items, I cannot add any new ones.

Backup your PST file. Search your computer for a file called scanpst.exe and scan your PST and see if there are any errors. Please make sure you BACKUP your PST before scanning.

Try creating a new profile and opening the PST from that profile and see if your old profile got corrupted.
