Is there a way to view calendars between users on an Exchange 5.5 server with users on an Exchange 2003 server?
I have a deployed Exchange 2003 server that is currently migrating users from Exchange 5.5. This 2003 Exchange server needs to communicate with another Exchange Server across a WAN link in order for users with mailboxes on both servers to view each others calendars and share resources. The Exchange 2003 server is on a Windows 2003 domain that has an established windows trust with the NT4 domain hosting the Exchange 5.5 server.
Please let me know is this is possible, level of difficulty in implementing the solution, and directing me to any resources or white papers that can help.
