I just ran into this bizarre error in Outlook, that told me absolutely nothing – the detail says Unknown Error (it also refers to a messaging interface). This particular beauty came up while sending and receiving while I was trying it – may have occurred at other times as well. Somewhat surprisingly, I found the answer quickly – at Microsoft! I did actually search at Google – but the answer was on a Microsoft page. I went back and searched using MSN Search and it also came up with this KB article as the first result. Promising!

This was resolved for one of our Outlook users by renaming the OST file and letting Outlook rebuild it.
