Before you use Exchange Mailbox, you must create an Email Journaling App. The Email Journaling App stores the configuration information for all the access nodes that are associated with it, and coordinates data protection operations for different access nodes. The Email Journaling App is also referred to as a pseudo client.
Before You Begin
You must specify the Name Server (domain controller). For more information, see Adding an External Group.
To improve the performance of archiving and cleanup operations, each Email Journaling App should have a service account hosted on it.
