My problem:
The messaging interface has returned an unknown error. If the problem persists, start Outlook again.
and Microsofts awesome suggestions
::RESOLUTION::
This problem may occur if you have exceeded the built-in .pst size limit. If this is the case, you may be able to work around this problem by using “Allow upgrade to large tables.”
If the “Allow upgrade to large tables” does not solve this problem use the following troubleshooting steps:
• Empty the Deleted Items Folder.
• Use the Inbox Repair Tool.
• Create a New Personal Folders (.pst) File.
• Create a New Profile.
• Install a New Set of MAPI files.
• Reinstall Windows. !!WINNER!!
FANTASTIC IDEA!! I think I’ll go ahead and Reinstall Windows for a .PST problem
UPDATE:: all i had to do was run Scanpst.exe and it fixed my issue
