Exchange 2013 won't connect to Outlook 2010 after migration

I just finished migrating from Exchange 07 to Exchange 2013 in a test environment.  All mailboxes have been moved over and the Exchange 07 server has been uninstalled.  OWA works fine for all users.

My issue is the Outlook 2010 client.  I created a total of 5 test accounts.  I successfully logged into the Exchange 07 mailbox for 1 of the acconts and sent some mail to all other users in the Org.  I then migrated ALL mailboxes over.

Once the migration was complete and the 07 server was decommissioned ONLY the account that I successfully logged into prior to the migration works via Outlook.  The other users launch Outlook, start the wizard, their info auto populates, and then they get prompted for credentials.... These credentials fail and I am stuck.

I have verified the credentials are good.  And using the same XP computer to test all the accounts... the only one that works is the profile that was already existing during the migration process, before and after.

I hope this makes sense.... PLEASE HELP!!

2013 uses RPC over HTTP protocol. Also XP is not the recommended for Exchange 2013. Follow this
