****UPDATE*****
it only happens when I have the option Use Outlook Web Access Light checked off.
Unfortunately being on a mac most of the time, I can not remove this check box.



my company has a webmail site.
I used to be able to goto it.
We migrated my mailbox to office 365. I was still able to goto webmail, just through new 365 portal.

I was migrated back to on-premise exchange server 2007 and for some reason I can not login to our webmail site on any of the machines I have previously logged on from.

I have tried all 3 of my machines with 3 different browsers on each and I get the same error after entering my credentials. If I log in with another users account, i get to their mail.

If however I goto a machine that I have never used webmail on, I am able to login as myself.
I have tried erasing all previous internet settings, flushed dns, cookies, passwords. I just don't get it.
Anyone have any ideas?

THank you in advance.


The error pops up after I enter my credentials.

"Outlook Web Access encountered an unexpected error and was unable to handle your request."
