After we reinstalled Exchange 2007 Server, it lost communication with Unity Server. How could we solve this problem?
We appreciate your help.
Make sure you run the Unity 5/7 script on the Exchange 2007 server to create the mailboxes on Exchange. There 3 mailbox accounts that have to exist on the Exchange 07 server for Unity to function.
This is in addition to the 3 functional account that you use with PW.
