I have outlook 2007 running on my pc windows 7 and have been running this for some years. I have noticed that I have an issue with deleting old emails.
After much messing about I have moved two sub folders into my deleted items bin but trying to remove them from there gives me the most helpful message' the messaging interface has returned an unknown error'
I have no viruses on my pc, ScanPST finds no problems, I can delete everything but these two sub folders, even if I move them back into my personal folders.If I select individual emails in these folders, I get the same message. If I go email by email, I am however able to delete any attachments the emails might have.
My .pst file is around 1.2gig in size.
At a loss of what might be the problem?
