I am attempting to set up EAS with a zimbra account and when I do so I get the message "not trusted certificate." I had the network's administrator send me a certificate. I connected my Pre as a usb device, placed the certificate in the Pre, but not in any folder.

I disconnected the Pre from the computer, opened the launcher, opened applications, went to preferences, went to certificate manager, clicked on the "+" in the lower left hand corner, it immediately brought up the certificate I just installed, and then I touched that to trust/install it.

It does not accept/trust/install the certificate and add it to the others that are there already.

Any ideas on what I need to do?
