E.g., 2 users have auto-reply configured. User A sends a message to User B. User B's auto-reply gets sent to User A's mailbox. That, in turn, causes an auto-reply to be sent from User A and insanity ensues.
How does Exchange 2010 prevent this scenario?
Also, can Exchange 2010 prevent a user's mailbox sending more than one auto-reply to the same user in one day?
Bonus: Assuming Exchange prevents this, how do I configure the settings?
Auto replies only get sent once per sender, per activation. There is no auto-reply loop with Exchange systems. Microsoft KB
the header is
x-auto-response-suppress:allis sent by default on auto replies. That in conjunction withx-ms-exchange-inbox-rules-loop(which contains the sender email address), should resolve any potential loop conditions.You can get around the one per sender restiction. In auto reply create a rules and a template and set as reply to all The sender will receive 2 emails on first contact. Then just one on second contact.
