Usage: UNDEL <memo number> [<folder>]

This command will allow you to undelete a memo that is currently in your RECYCLER memo box. You will need to change your active folder to the RECYCLER folder and then LIST so you will be able to obtain the memo number. The undeleted memo will be automatically moved back to the INBOX memo folder unless you specify a folder.

/msg memoserv undel 1 SYSTEM /msg memoserv undel 2

If you accidentally delete a memo but have not yet expunged your RECYCLER, you can get the memo back. This is most useful if you accidentally sent the delete command. But you should try not to count on undeleting memos to get them back.
