Has anyone else run into this problem.

We've got some users with Windows Mobile 5 devices. When they try to synch their email using OMA (with SSL) they get an error that the SSL certificate is not valid (which it is). If they leave SSL un-checked, it works just fine. Obviously this isn't the way we want to be doing it.

Both the server hosting OMA and the devices themselves have legit certs (from VeriSign).

Thanks.
