You must use a Network Time Protocol (NTP) server within your network to synchronize the time of the System Platform server. The Avaya message store server and the Message Mirror server must synchronize with the NTP server.
Message Mirror does not replicate the following:
System broadcast messages
System lists such as ELAs and PDLs
Messages stored in a folder other than the Inbox folder
Future delivery messages that are stored in a queue
Application layer data, including sites and topology
Administrative logins
Nightly backup schedule
Certificates
Messaging does not support Message Mirror when:
the application server and the storage server are active on the same server, that is a single server configuration.
the single server configuration has additional application servers.
all application servers are not duplicated.
the Microsoft Exchange server is used as a message storage server.
