Get a list of all disconnected mailboxes in Exchange 2010

The following script cleans up all your Exchange databases (necessary to get a fresh list of all disconnected mailboxes) and creates an HTML and CSV file containing:

  • DisplayName of the mailbox
  • ServerName, on which the mailbox is stored
  • DatabaseName, in which the mailbox is stored
  • DisconnectDate, when the mailbox was disconnected from the user account (the HTML output is also sorted by this column)
  • DisconnectReason, guess it: why the mailbox was disconnected (i.e. because the user account was disabled)

Just copy&paste these lines into a powershell script:

# ExportDisconnectedMailboxes.ps1
# This script runs "Clean-MailboxDatabase" on all
# available databases and creates an HTML report
# of all disconnected mailboxes.
