Question : Exchange 2003 ActiveSync and OMA

We have recently upgraded to Exchange 2003 SP2 and I am trying to use Exchange ActiveSync with Direct Push to get email on a Windows Mobile Device.

The problem is that for Outlook Web Access we are using SSL (with a Certificate created using Certificate Services) and I can't disable SSL on the site to allow Microsoft-Server-ActiveSync and OMA access.

So I found the Microsoft Knowledgebase Article KB817379 which should somehow fix it but we're still getting 0x80072F17 and 0x85010014 errors on the Device

The Exchweb Directory is set to require SSL
The Exchange Directory is set to require SSL
The Exadmin Directory is set to require SSL
The OMA Directory is *not* set to require SSL
The Microsoft-Server-ActiveSync Directory is *not* set to require SSL
The exchange-oma Directory is *not* set to require SSL (set up using KB817379)

Also, if I try and browse the OMA folder (http://servername/OMA) then I get the following message:
Unable to connect to your mailbox on server . Please try again later. If the problem persists contact your administrator.

I think we should be able to browse this folder?

If anyone can offer any assistance or let me know some other things I need to check that would be great.

If you are concerned about security, then simply block port 80 traffic coming in. The call on http is internal only. On the sites that I build and maintain I only allow two port in - 25 (SMTP) and 443 (HTTPS) - nothing else.
