Seems you really don't need this mailbox and user anymore. The most simple method? Fully delete mailbox and email address. Anyone sending mails will receive a "No such user here" bounce.

Kimputer, you are correct but guidelines we have in place do not allow us to "delete" the mailbox so that unfortunately is not an option. &nbsp;Thanks,<br><br>

I have a terminated user's email account in exchange that was converted to a "shared" mailbox and that user's email was set to forward to another user. &nbsp;Now that months have passed, I would like to setup this mailbox so that anyone that sends an email to the terminated employee receives an "undeliverable message" - I know how to remove the forward but not sure about how to get the "undeliverable message" sent to anyone that sends this terminated employee an email.&nbsp; Please advise how this can be accomplished on the terminated user's mailbox. &nbsp;I did see a post from 2016 that addresses this issue somewhat but not sure if anything may have changed since that post.
