I've done this a number of times on SBS 2003, but now I have to setup a Windows Mobile 5 device to sync with Exchange 2003. This is Exchange running on 2003 Server Standard, not SBS.
I have created a self-signed certificate on the Exchange server.
I can login to https://servername/exchange
and use OWA.
I can login from the WM5 device and use OWA.
I have exported the certificate (using a variety of methods) and installed it on the WM5 device.
I can go to certificates on the WM5 device, click on the Root tab and see the certificate.
Every time I try to sync with the Exchange server, I receive a 80072F0D error. Everything I find about this error indicates the certificate is invalid on the server, but the certificate works fine for OWA.
I've tried a Cingular 8125 and the MS Pocket PC Emulator. I get the same error on both.
Can anyone out there offer any suggestions on how to troubleshoot this error?
