I am testing Outlook Mobile Access on a Windows Server 2003 Small Business Server with no service packs installed for Exchange 2003. This will be used on a Motorola Q phone, however I use the following address in Internet Explorer for testing:
When I log in to this address above (using the correct domain, obviously) as the domain adminstrator I get to a page that says my device is not supported (which is fine because I'm using IE which is not a mobile device), at that page I click OK and then the regular OMA page comes up (Inbox (#items), Calendar, Contacts, Tasks, etc.) just fine.
The problem is when I try to log in to the same page as any other domain user. Instead of going to the "device unsupported" page, the following page loads:
Item no longer exists. The item you are attempting to access may have been deleted or moved.
I'm not using MSFP or SSL. The fact that it only works for administrator seems to suggest a permissions problem, but Outlook Web Access works just fine for every user. I checked the "Exchange Features" tab in SBS' System Manager, but each one had all Mobile Device features Enabled.
Let me know if I can provide any more info on the setup of the server!
