I am using exchange 2003 sp2 front end server to access exchange 2003 sp2 standard backend server. I can access owa by going through the normal router https://mydomain.com internally and externally but when i try to add this to a cell / mobile using active sync it just doesnt work, nothing at all.

I thought I would check the IIS settings and compare them to an exchange server that already works ok but this looks the same.

The only difference is that this one is in a totally different domain.

So that you can get an idea of the structure im in, i am based in site 3, and i am a child of site 1 that resides in forest of company. Site 2 is also a child domain just like me
So my FQDN is site3.site1.msft.
Users in sites 1,2 and 3 can all see owa and recieve active sync ok
Site 4 is in its own domain, of which there are domain trusts in place. I can connect via owa to their exchange server but not by active sync

I dont even know where to begin. I hope I have explained it ok, buit if you need any more information please ask. all servers run on windows 2003 sp2 standard x32
