****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."

Exception
Exception type: System.IndexOutOfRangeException

This is what I had to do to fix it.
1) Run MFCMapi
2) Session menu > Logon and display store table
3) Logon to the user's mailbox
4) Double click on the row for the user's mailbox (it should say something like
"Mailbox - Username")
5) In the tree to the left, expand "Root Container" and "Top of Information
Store"
6) Right click on "Inbox" > "Open Associated Contents Table"
7) This will open a window which you may need to resize to see all the columns.
8) Find the row with message class "IPM.Configuration.Owa.BasicFolderOption".
9) Right click on this message and choose "Delete Message"
10) Leave "Delete to Deleted Items" selected and press "OK"
