I just brought a new Exchange 2000 server online, our current exchange server is 5.5. I migrated over a couple of test accounts just to make sure it works, i would now like to migrate over just the IT Dept for about a week so that we can test. Outgoing mail works fine unless it i to an account on the other server, and I get no incoming messages. Is there a way to forward incoming mail that doesn't have a mailbox on out 5.5 server to the new 2000 server ? If so how ?
