I have a rather unique problem in where I'm trying to find the solution for. We have an exchange server at work, but our administrators do not allow pop3 or imap connections to it; just plain old Microsoft connections through Outlook. They do, however, have OWA and ActiveSync running fine.
I'm having issues trying to use Thunderbird, Mail.app, and syncing it with my phone. Basically, I need a pop3 or imap server. This is where I am thinking about Zimbra.
Is there a way to 'fetch' mail and calendar items from the exchange server and have it import it into zimbra automatically using something like OWA or activesync?
I've tried to look around but haven't seen much about this at all. Any help or guidance is appreciated.
