Using Messaging, you can configure multiple storage destination types for your Messaging system. You can use the following storage destinations to store your voice messages.
Avaya message store: This is a built-in storage. To set up a storage role, see Initial administration checklist for the storage role.
Microsoft Exchange 2007 or 2010: To configure Exchange as your storage destination, see Configuring a storage destination.
You can designate a storage server on a per user basis, allowing for a mixed environment of Avaya message store and Microsoft Exchange email servers.
The time setting on the application servers in the Messaging system and the configured storage server must be in synchronization. Even if the servers are in different time zones, the timestamps in UTC must match.
Hence, even if the time difference between the storage server and the Messaging server is only a few seconds in UTC equivalent, the Messaging system suppresses the outcall notifications on the messages.
Messaging supports either Microsoft Exchange 2007 or Microsoft Exchange 2010 as the message store. Messaging does not support Exchange Online. Messaging supports Active Directory provisioning.
You can use the Active Directory look-up utility to import user data into the Messaging directory. From the Active Directory, you can source user properties, such as mailbox, extension, and site information, based on the work phone data in Active Directory. Using the existing Active Directory means the most relevant user data, such as name or telephone numbers, is available for use by Messaging.
