I just received a 700wx that replaced one that went bad. I had active sync connecting with this same Exchange server working fine.

When I sync, of course i got the "Your server's certificate is invalid...." (also, when i browse to OWA with IE i get the "invalid certificate" warning page.

So, I went to the Exchange server, in IIS exported the certificate in a DER x.509 binary file. Copied this file to a memory card, then on to the palm. Tapped on it and it asked me if i was sure I wanted to install. I said yes.

In Start - Settings - System - Certificates - Root, i can see the certificate is there, and it looks just like it does on the server.

BUT, i still receive all the invalid certificate errors/warnings both when i Sync and in IE.

What did i forget to do?
