I have Outlook 2011 for Mac installed in my MacBook Pro. It was working great for 2 years but now a problem has come up. I have an IMAP account setup with it (it's hosted through GoDaddy), and everything syncs fine except for the Sent Folder. The e-mails that I send through my Mac do not show up in the e-mail server thus they don't show up in my other devices (IPad, Android Phone, and Windows 8 Desktop). All the other e-mails that are Sent through my other devices show up in the e-mail server and even show up in the Outlook 2011 for Mac folder.

As you can see the problem is only with the uploading of the Sent message from my Mac. A message at the bottom of the Sent Folder says "Sync Pending on Folder". I click on it and the Progress Window pops up, it says E-mail (IMAP) Sent: Uploading 0/200 messages. It does not upload anything and just disappears after a few minutes. I tried changing the Outgoing Server to all the available options but nothing has changed.

Any suggestions? Thank you in Advance.
