SBS, SSL Certs and Verizon's Treo 700w
So, there has been a decent amount of rumblings about the new Palm Treo 700w from Verizon Wireless (running Windows Mobile 5.0) - and it's apparent inability to sync with SBS.
Sean has a good post outlining how Windows Mobile 5.0 has changed how it handles certificates. The good news is that if you're using self-signed certificates with your SBS, you can get your Treo 700w to sync wirelessly with your Exchange server. As proof, I just did this myself - configured a new 700w for one of our internal users to sync with our SBS, and we're using a self-signed certificate.
The trick is to install both your self-signed certificate ( \\<your_sbs\ClientApps\SBSCert ) AND your CA certificate (publishing.company.local - check out \CertEnroll">\\<your_sbs>\CertEnroll ). Copy these two .cer files to your device using ActiveSync. Then on your device, use FileExplorer to browse to the folder where you copied the certs, and double-click to install each. Voila! You're good to go . . .
Now, there has been some talk that WM5 doesn't trust as many Certification Authorities (CAs) as regular ol' Windows. As a result, if you have purchased an SSL cert from a CA, there is a chance that CA may not be trusted by WM5. In that case, you're not going to be able to sync with your Exchange, since you won't have access to the CA cert to manually install it on your WM5 device. However, you could always convert to a self-signed cert and get it to work that way
