Exchangeis the message store, the messages are stored in the appropriate user's inbox.
In case of a Voicemail only Unity server, exchange is installed in the Unity box itself (typically, though Exchange can be installed offbox too). In this case voicemails will be stored in the Unity server itself.
In case of Unified messaging (or voice messaging with offbox exchange) , the message store has to be installed offbox, which means voicemails are stored in the Exchange server.
When the connection between Unity and Exchange is broken, Unity starts storing messages in UMR (local to the Unity server) and when the connection is restored, it pushes the messages back to Exchange.
