We are currently running an Exchange 2003 environment and Unity 5.x. We are migrating to Exchange 2007 SP1 on a different server. We want to be able to do a phased migration to Exchange 2007.
Can Unity send voice mail messages to both servers.
User A on Exch 2003 ->Move Mailbox to 2007. Unity is currently pointing to 2003 server.
Can this scenario work? If so, any documentation would be helpful.
