I cannot successfully get versamail to sync with our Exchange 2003 server.

I keep getting this:

error: There was a problem with Syncing. Server certificate domain does not match server. Contact your administrator if this error persists.

Detail: AirSAMAstateMAchine.c 530 4670 error


I'm not using SSL, I have un-checked that box, and I am not using a proxy.

Any help would be appreciated.
Thanks.
