Fixing “Outlook(R) Mobile Access is supported only on Microsoft(R) Exchange Server 2003. Currently your mailbox is stored on an older version of Exchange server.” on Outlook Mobile Access under Server 2003
This article is now 14 years old! It is highly likely that this information is out of date and the author will have completely forgotten about it. Please take care when following any guidance to ensure you have up-to-date recommendations.
So I was testing the configuration on my Exchange 2003 server in preparation for the roll out of some Windows Mobile devices when I recieved the following error:
Outlook(R) Mobile Access is supported only on Microsoft(R) Exchange Server 2003. Currently your mailbox is stored on an older version of Exchange server. Please contact your system administrator for additional assistance.
“That’s odd”, I thought, “I only have Exchange Server 2003 in my organisation, how can I have an older version of Exchange?” It turns out that this has nothing to do with the version of Exchange you are using. I have set up my Exchange OWA to require SSL (see previous article on SSL and Integrated Authentication) and apparently this can cause issues for OMA.
The Microsoft-Server-ActiveSync and Outlook Mobile Access virtual directories
cannot access the contents of the user’s mailbox if the Exchange virtual
directory is configured to require SSL. The Microsoft-Server-ActiveSync and
Outlook Mobile Access virtual directories only try to connect with the Exchange
virtual directory over TCP port 80 (HTTP), not over TCP Port 443 (HTTPS).
To resolve this, you need to follow these steps from MSKB 817379

Additionally, you must use Internet IIS Manager

Access to work. If you are using Windows Server 2003, follow these steps:
