If you disable the "require ssl" on the FE servers, can you connect to them?
Just as a test?

Subject: [ExchangeList] IMAP Testing issues - any help appreciated
Hello all -
long story short, I am now having to implement IMAP (SSL - 993) access
for our environment. I have a few issues. Any info is much appreciated.
Info -
Running Exchange 2003 in FE/BE scenario.
FE Servers are Network Load Balanced with Forms Based Authentication
BE Servers are two Active/Passive Clusters
I have enabled IMAP in Exchange on both the FE and BE servers as well as set
the IMAP service to Automatic (and started)
- On the FE servers, I have 'require SSL' under the Authentication
requirements
- Port 993 is open on the external firewall to the FE server IP
On the BE servers, I have not required SSL in the Authentication
Requirements ( What I have read indicates this should not be selected)
Results -
- I can connect via IMAP when connected on the internal network over port
143 directly to the Backend Server. Port 993 does not work (and
shouldnt...)
- I can NOT connect via IMAP when connected on the internal network over
port 993 when specifying our OWA server address (owa.globalknowledge.com)
- I can NOT connect via IMAP from outside the internal network over port 993
when specifying our OWA server address (owa.globalknowledge.com)
Once again, port 993 is allowed on the firewall and all services are
configured and running. What am I missing?
The Outlook client connection errors that I am getting are:
Task 'Checking for new mail in subscribed folders on
owa.globalknowledge.com.' reported error (0x800CCC0E) : 'Outlook is unable
to download folder (null) from the IMAP e-mail server for account
owa.globalknowledge.com. Error: Unable to connect to the server. If you
continue to receive this message, contact your server administrator or
Internet service provider (ISP).'
Task 'owa.globalknowledge.com: Folder:Inbox Check for new mail.' reported
error (0x800CCC0E) : 'Outlook is unable to download folder Inbox from the
IMAP e-mail server for account owa.globalknowledge.com. Error: Unable to
connect to the server. If you continue to receive this message, contact your
server administrator or Internet service provider (ISP).'
