In an effort to make user terminations and layoff as simple as possible, I wrote an Exchange Powershell script to do all the important tasks. My script does the following:

  • Moves the account to the “Inactive Users” OU (We never delete user accounts once created…)
  • Sets the description attribute of the AD account to “NoSearch” (Our email-enabled network scanners are configured to ignore accounts with NoSearch in the description field)
  • Lists and deletes user-created inbox rules that forward email to outside accounts (to prevent data leaks and possible espionage)
  • Hides account from Exchange address lists
  • Moves the mailbox to the disabled accounts database
  • Removes the user account from group membership, and creates a log of the groups the user was a member of (useful if the user is laid off and will be returning at a later date)

This script does not prompt for a forwarding address, but could be easily configured to do so.  Instead, it reminds you to configure one at the end of the script.

 

The script takes a single argument, the alias of the account being disabled.

$user = read-host "Enter user account to disable"
