Split From: "MAC OS X 10.7.3 and MS Outlook 2011 - "Could not change to that identity" error"

I've gotten the same Outlook error with a brand new (as of today) Mac and a brand new install of Office 11 for Mac. 

None of the solutions has helped.  I've rebuilt the database, deleted all identities, updated Office, tried Outlook with a new user account (for the Mac) and moved the Office Identities folder to the desktop. 

I still get the same error with Outlook.  All of the other applications launch OK.

Apparently, then, the issue is not with my User folder, but with the MS Office files themselves.

I can't think of anything else to do except uninstall Office and start over, or find an email client that might actually launch and work.

This is beyond extremely frustrating.
