I have an Exchange 2003 that users access using Outlook Web Access. Some users within the office use Outlook 2000/2003 which they access the Exchange server within the LAN. We just received a batch of Sprint Blackberry phones along with some Pocket Pc's. I need to configure then to access their emai via IMAP but am not sure where to start or how to get the ball rolling. Things that I have done are the following: the IMAP service is running on the exchange server, I issued a certificate to the IMAP4 virtual server and the ports are open on the firewall. I need help and am stuck as to what to do. Thanks in advance for all the help and suggestions.
