Palm / Windows Mobile / Exchange Active Sync
I just did my first Exchange Active Sync configuration.
Here’s the procedure:
1) Make sure you have a valid cert on your site. https://FQDN/exchange should NOT give you an cert errors. If you do insist on using a self-signed cert, it requires saving the cert to a XML file format, sticking that XML file into a CAB file, and then transferring and installing that CAB file on the mobile phone (Windows Mobile only). Use a cert from a recognized certificate authority. Here are some KB’s on it:
2) Make sure you have port 443 open on your router and directed to your Exchange FE server.
3) You will need to follow the following KB to get Exchange AS to work on Exchange server 2003 Standard and Enterprise: http://support.microsoft.com/kb/817379. Note that if you have SBS 2003, Microsoft has kindly already taken care of getting it to work. This site http://www.amset.info/exchange/mobile-85010014.asp also has some valuable content. Basically a reproduction of KB 817379, except he gives some additional steps that I used - but don’t know if I would have had to or not!
4) Finally, go to your mobile phone and setup ActiveSync to the FQDN of your Exchange server. This should be public DNS resolvable.
Finally, let me add that my synchronization of Windows Mobile was totally smooth. Getting the Treo 755 (Palm OS) to work was a bit of a challenge. However installing Exchange SP2 ultimately resolved that problem. To determine the Exchange Service pack level, go to Exchange System Manager and right click on your server. You should see the service pack level under the “General” tab of “Properties.”
