Need assistance on a general direction.
There is a 2003 domain with exchange 2003 currently in use. On this domain there is also a contact management application that is heavily integrated and cannot be update at this time. I would like to bring up a new 2013 exchange server.
Is there a method that I could have user data synchronized between the 2013 exchange data and the 2003 exchange? In this manner users could use the 2013 exchange as primary and the Contact manage application could use the sync copy of exchange 2003. For now I am only concerned about he the calendar however I am sure the other information will need to be sync as well.
Please let me know. Thank you.
