We setup an Exchange server or a client that basically wants to make sure all mail sent to subscribed Blackberry phones are kept secure and no one can access them. We installed Blackberry server and PGP server and they seem to be working fine.
The issue, as we understand it, is that Exchange still keeps a copy of the emails (and we don't want that for security reasons), and also we understand that if we delete the emails from Exchange, then Blackberry users can't forward or respond to emails any more, because connection to Exchange is required.
1. Are the above assumptions correct, that we need to have a copy of emails on Exchange in order to be able to forward/reply to emails from Blackberry?
2. We need a quick solution/scripting to allow deleting emails from Exchange based on a configurable time frame (from example, delete emails older than 1 hour, 24 hours, 240 hours, etc. -- somewhere to configure the number of hours for age of emails before getting deleted).
3. We also need to make sure data in Exchange in encrypted and no one can access it, even the administrator of Server. Can we protect against the Exchange admin also?
