Microsoft Exchange 2003 – Move Mailbox

Introduction to Move Mailbox in Exchange 2003

Once you have sorted out Active Directory and the ADC’s, you are ready for the final leg of the migration journey – to move the user’s mailbox store to the new Exchange 2003 server.

Topics for Exchange 2003’s Move Mailbox


New features supplied by the Move Mailbox Wizard

The wizard provides a method for moving mailboxes from within Exchange 2003’s System Manager.  (If you prefer, use the Active Directory User’s and Computers.)  How ever you access the mailboxes, here are two very useful new features :

  1. In Exchange 2003, you can select multiple mailboxes
  2. I recommend the task scheduler, so that you can plan now, and move later.

For example, you can schedule a large move to start after workers go home, thereby ensuring that your server’s resources are not being stressed during business hours.
