[Citadel Support] Setting up Outlook as a client

[jsuber]

I can only connect to my Citadel server using my [EMAIL PROTECTED]
login.  I am using IMAP.  When I setup [EMAIL PROTECTED], Outlook with prompt
me for my username and password.  Same is true for all users I created.  I
gave them the same rights as my administrator account. Any suggestions? 
Thank you for your help.  Jon
