My sent items box was just too large (approx 2Gb big). Thanks + 0 Votes Message stuck in outbox and resending solution rambo626 6 years ago I had the exact same problem to the letter. Every forum tells you to delete the outbox.dbx file, but in fact you may need to make room in your sent items folder. The cause for the problem may in fact be that there is no room for the message to transfer into the sent items folder. I actually just backed up my sent items and deleted the sentitems.dbx file and the outbox.dbx file together. It fixed the problem right away. post a reply if it worked.
