Please describe the problem:
With exchange 2003 and any version of connector above 2.2 including 2.4.1
connector will not configure account when username and mailbox name differ.
Works OK on earlier versions of connector whick allow entry of different names.
WEB Outlook works with same account.

Steps to reproduce:
1. Try to set up evolution account to exchange when username and mailbox name differ
2. 
3. 


Actual results:
Could not configure Exchange account because an unknown error occurred. Check
the URL, username, and password, and try again.

Expected results:
account setup complete and forward button activated

Does this happen every time?
YES

Other information:
This prevents us from using Evolution and forces continued use of WEB Outlook.
