The user has not been renamed, but the Alias was apparently changed at some point. Provided the login name as you suggested and it immediately connected.
Thank you.

Question
Exchange 2003 IMAP connection refused for one user only
It's going to be difficult to remember everything I've tried, but I'll do my best.
My Exchange 2003 server accepts IMAP connections. This accommodates unified communications with our phone systems which send voice mails as WAV files via SMTP, then connect via IMAP to check the status of those messages. The client computers use Outlook over MAPI for their email client.
This is working for all but one user and I have been unable to determine why that one user is refused an IMAP connection.
In ADU&C the user's Exchange Features are all "Enabled". In Service Manager the IMAP4 Virtual Server does not limit the number of connections nor does it limit connections from IP addresses. NTLM authentication is enabled as is Basic authentication.
I've attempted IMAP connections for this user from the phone system, from Outlook, and from Thunderbird. All have the same result; the connection is refused.
The user's login name is "johns". The user object name is "John Smith". I've tried a variety of combinations including "johns", "mydomain/johns", "mydomain/johns/John Smith", and several others that don't come immediately to mind. I've had success connecting to IMAP with several of these types of combinations as other users.
Anyone have any idea what could be causing this? Is there an IMAP log on the Exchange server somewhere that will tell me why the connection is refused?
Thanks in advance,
Lane Beneke

It should be DOMAIN/User/ALIAS - not display name
In the user account, have a look for the Exchange Alias (on one of the Exchange tabs) that should be the last item in the full username.
This is only a problem because that account has been renamed at some point (presumably)
