I'm having trouble with stuck messages in my outlook outbox. When I try to delete them I get the following error message: " The messaging interface has returned an unknown error - if the problem persists restart outlook" - which I have tried to no avail.
I can open the messages and hit resend. One of the messages is being sent repeatedly but the send/receive status always end in an error before it reaches 100%.
I can't drag them to another folder either.
The original group of four messages included attachments (.3 to 3MB) and my wireless popped offline during the original send - when only 2 out of four ended up sent.
