Outlook Error 50

[TPCK1]

I have a user who continues to get Error 50 when using Outlook 2011 for Mac.
User can send and receive mail without any issues - just pops up error message in the corner that there are errors and if you open those errors up doesn't say much but gives you error 50
I've gone thru and uninstall/reinstall Safari, updated Safari, uninstall/reinstall Office and repair permissions as most websites were suggesting but still no luck.
Again user is able to send/receive mail but just keeps popping up this error - more of a nuisance. Any insight would be greatly appreciated, Thanks.

An unknown error (-50) occurred

One user found this solution: Run "Remove Office", then run Repair Permissions. Install from your CD and apply all updates. Restart and then run Repair Permissions again. - Tried is already still got same error message

Another cause for this error was found by J. Gorman: I had a semicolon in my outgoing server name. - server name is correct no extra characters.

Another user reported this fixed the issue for them: Try creating a new Entourage identity and setting up your email account. When the email address is verified with the new identity and you receive your e-mail, then try switching back to the identity that you had a problem with and check your mail. This solved the problem for me. - Entourage was never setup or configure on this machine. Outlook is the only mail client that is being used.


Christoph Nadig, reported this solution: I found old mails in my outbox that were never delivered (for an unknown reason), but everytime I wrote a new mail, Entourage tried to send them again, leading to a -50 error everytime. Deleting these old entries in my outbox resolved the problem. - no old emails.
