How to Remove Mailbox Exchange
Removing mailboxes helps reclaim and recycle storage space. (hard drive interior image by Curtis Sorrentino from

Mailbox management typically refers to the strategy and policies you (as an Exchange administrator) and your corporate management create around managing retention and storage space of your electronic mailboxes. Mailbox removal is one process you should define as part of your mailbox management strategy. Removing mailboxes allows you to delete unused or unneeded mailboxes and recycle for other purposes the storage space previously consumed by those mailboxes.

Tips and warnings

  • If a mailbox has been disconnected from the Active Directory object, but has not been completely removed, you can reconnect it. For more information, refer to Managing mailboxes in Exchange Server 2007 ( in Resources.
  • In Exchange 2000 and 2003, the mailbox may not be immediately removed depending on the "Deletion Settings" for your Mailbox Stores. To remove the mailbox immediately, you may need to run the cleanup agent and then purge the disconnected mailbox.
  • In Exchange 2007 and 2010, be mindful of the difference between the "Delete" and "Remove" options in the Exchange Management Console. Selecting "Disable" removes all Exchange attributes from the active directory account and marks the mailbox for deletion. Selecting "Remove" deletes both the mailbox and the associated Active Directory account. This may seem backward, but it is the correct functionality.
