|The other place in my outlook that can be editted is to right click on "Mailbox - USERNAME" (or personal folder) --> properties|
Click homepage tab, then restore defaults.
Essentially in my previous email we were telling outlook to select the Mailbox - Username (or personal folder) folder as the default to be shown on startup.
But if the address in that folder has been altered, then it will not work properly.
Let me know if it worked for you.
Unfortunately that is all i can think of, and i am working in an exchange environment,
