I have a T-Mobile MDA and I am trying to set it up with an exchange server. I think I have all of the peramiters right but when it connects up I get the following message: "The security certificate on the server is invalid. Contact your Exchange Server administrator or ISP to install a valid certificate on the server". The problem is that the company I work for will only help me if I have a Blackberry device. I know that I can make the phone accept the certificate but I just don't know how. Any help would be great.
