message tracking - permalink - collapse

All > Technology > E-mail > Microsoft Email > Microsoft Exchange > Microsoft Exchange 2007

The tracking of events from the time a message enters an Edge Transport server or Hub Transport server to the time it leaves the any of the Edge Transport servers or Hub Transport servers in a single organization. Message tracking logs capture data from all stages of a message's journey through a server. Message tracking logs can be used for message forensics, mail flow analysis, reporting, and troubleshooting. By default, message tracking is enabled on each Exchange Server 2007 computer that has the Hub Transport server role, the Mailbox server role, or the Edge Transport server role installed. Message tracking can only be enabled on Exchange 2007 servers that have these server roles installed, because these servers participate in message routing and delivery. [Exchange 2007]
