SBS Exchange IMAP Connection Problem

I am having problems establishing a connection to my SBS Exchange Server via IMAP using Outlook.  When I test my connection in the setup screen, it will ask for my login and password 3 times and then error out.

The error given is:
Log onto incoming mail server (IMAP): THe connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service providor (ISP).

My SBS Exchange Server setup:
-I have setup my server using the information in the following link:
-IMAP Services is enabled (automatic) and started
-Ports 143 and 993 have been opened in the SBS firewall (we have a 2 NIC server using the SBS firewall only)

My Outlook setup:
-Incoming and Outgoing server address is the same address we use for OWA and RWW
-Login and Password is the same used when logging into OWA or RWW
-Under the More Settings... option
 *Outgoing Server Tab: My outgoing server (SMTP) requires authentication option is checked (and I am logging in using the same login and password as OWA or RWW)
 *Advanced Tab: Incoming server (IMAP) is set for SSL and port 993 is listed

It appears that the connection is initially established because when I test the connection in the setup screen it asks to verify the certificate (The server you are connected to is using a security certificate that cannot be verified. Do you want to continue using this server?). I select Yes, which is when it asks for my login and password (3 times) and then fails.  Also, when I check the event log on the server, it shows successful logins from the remote computer using my login.

The SMTP outgoing connection seems to work as a test message in the setup screen is sent and shown in my mailbox when I login to my mailbox locally or via OWA.

Does anyone have any suggestions or solution for getting my incoming IMAP connection to establish using Outlook?

Thank you!

Is there a specific reason you are trying to use IMAP? HTTP RPC using outlook is much slicker... http://www.amset.info/exchange/rpc-http.asp

In the end, I am trying to set up an iPhone to access the Exchange Server via IMAP (unless there is a better way).  I figure if I can get it to work properly through Outlook first, then I can get it set up on the iPhone.
If you're using an iphone, it should be possibleto use activesynch.  IMAP will present you with a problem when it comes to sending mail.  You'll have to allow external devices to relay through your SMTP connector.  Granted, you can restrict access to users that authenticate, but given the choice, I'd rather not even expose my internal SMTP in such a way.

Try the IMAP connection without encryption first of all - 143to try and eliminate that as a contributing factor.

If your domain account name is different to the mailbox alias, you need to supply the IMAP user name in the form:

Thank you!  That did it.  The prefix for my email address is different than the login; I did not know that would make a difference for logins.
