Using Microsoft Exchange Server 2007 Dial tone recovery feature - Part I

Part 2 is now posted here


We will see step by step how to recover from a disaster using dial tone database on an alternate mailbox server.


Exchange Server 2007 has many ways to recover from a disaster scenario and it takes advantage of the database portability where we can easily move database between mailbox servers.

 In this article we are going over to dial tone process that consists in a database corruption or server failure which the process to recover the server or database cannot be done in a reasonable time.  In this case, we can start an empty database to provide limited business continuity for the affected users.

The entire process that we will be going over in this article will be explained in three follow figures. First of all, our current scenario has some users that are connected to their respective mailbox in the Mailbox Server (Figure 01).

Figure 01: Active Directory users and their respective mailboxes

After a hardware failure in the Mailbox Server 01, we will move only the user configuration to a dial tone database located in the Mailbox Server 02. The users moved to this new mailbox server will not have any message on their folders. (Figure 02)

Figure 02: Moving the user’s configurations to the dial tone database

Then, we will follow these steps (Figure 03).

·         Recover the Mailbox Server 01 and its respective database from a backup

·         Step 01: Move the database from Mailbox Server 02 to the Recovery Storage Group on Mailbox Server 01

·         Step 02: Move the mailbox configuration to the old database

·         Step 03: Merge the information from the dial tone database (new messages) with the current database (database with all messages before the server failure)
