Question : Users whose usernames contain # cannot access OWA 404 error after authentication.

We have a standard in which temporary accounts or consultants have a (#) appended to their username - johndoe#@cs-americas-com.

While these accounts can access their mail through the Outlook client - they get a 404 file not found after entering the username\pass in OWA.

Exchange 2003 running on Windows 2003 Enterprise front end server running IIS 6.

URLScan.ini not found.

Please advise.

Answer : Users whose usernames contain # cannot access OWA 404 error after authentication.

# has a special significance in URLs, that'll be what's causing the problem.
