We're putting in Unity 5.0(1) with Unified Messaging with MS Exchange 2003 for the first time. We're getting the following error in the event log every couple of minutes.
Event ID: 30003
An attempt to access the Primary Exchange Mailbox Store by CsBMsgConnector via MAPI has failed. The MAPI subsystem return the following error: The information store could not be opened..
Anybody know how to fix this?
Our test messages are pilling up in the UnityMTA folder. Our Exchange is up. We can pull AD accounts into Unity as subscribers. We can't push into voice mails into Exchange. We can't retrieve voice mails that are stuck in the Unity MTA folder either.
