Exchange server standby solution using mailbox level replication with crossed replication between two active exchange servers

Abstract

This invention provides the capability to plan, monitor and control post-failure switching of user mail access hosted on Microsoft Exchange servers at the granularity of individual user mailboxes. It offers a convenient point-and-click mechanism for achieving a very complex task, and allows replication of e-mail data from a Primary Exchange Server to a Standby Exchange Server at a level of data granularity and flexibility not previously available. No limitations are placed on which Exchange servers belonging to the user of this solution are to be in a primary or standby role, and it is possible to have two Exchange servers, each acting as an active primary for mailboxes which it is hosting AND acting as a standby for mailboxes hosted on the other server. In addition, it also provides a uniquely powerful capability for migration of mailboxes between Exchange servers.
