  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.  

I have exchange 2003 installed so whats the deal.

    I have seen this error before.
    Have you done anything with OWA? Customise URL, move to another web site, anything like that?

    I have also seen it when FBA is enabled with require SSL. That is fixed either by MSKB 817379 or my guide here:

    So I created a new Virtual Directory and sync works.  Now I have exchange-oma and exchange with neither requiring SSL.  I do not see what creating an extra Virtual Directory does if they both are now not requiring SSL.  Am I suppose to delete the new virtual directory once I have tested?  Also im trying to get active sync to work so isnt the active sync going after microsoft-server-activesync instead of exchange-oma?

    Accepted Solution

    When you sync to Exchange, the ActiveSync process gets your mailbox data through an internal call on port 80 to the /exchange virtual directory.
    Having the require SSL option, no integrated authentication or other settings changes on the /exchange virtual directory causes that process to break. The /exchange-oma directory and the associated registry change alters where EAS gets its information from to a second virtual directory, which is pointing at the same data. The /exchange VD works as it always did allowing you to effectively have two different configurations for the same data.
