Thanks for reply. I found out how to make the rule that will purge any OOF that comes to the helpdesk mailbox. But if I go to my outlook, and creates an e-mail rule, that will reply to any e-mail sent to me (some users do this instead of using Out Of Office), I can not stop the loop.

Any idea on how to identify e-mails that have beeen created from an outlook rule?

    I ended up doing this with rules (in Office 365). One rule to prohibit Out Of Office replies to go to specific mailboxes and another that identified "auto-submitted" in the header of an e-mail and deleted this too.

    Only problem is that when the mail come from my old Exchange 2010, the "auto-submitted" is not added when the e-mail is generated by an Outlook rule. But this is good enough.

    Thanks for input.
