>From our testing, forward rules can cause a loop, if the forward is to external server. If the forward rule is set to send to a local exchange mailbox it will detect the loop and stop. But external connections will continue to loop until find it or the server runs out of space.
We had this happen in our environment a couple of years ago. I user had a rule set to forward all e-mail to their hotmail account. When they went over their limit it would send back bounce messages that were then forwarded to hotmail, and so the loop started. This happened over night and out server blew up because the queues have over 300,000 messages waiting to send and each time the message got bigger. So we disable automatic replies to the internet for the entire organization and told the users to use OWA to read mail. Out-of-Office does have the loop stopper by only allowing one reply every 24 hours. If you have automatic updates to the internet disabled then additional rules in the OoO will not go out. js * John Senter * Sr. System's Administrator * St. Jude Children's Research Hospital * 332 N.

Also, I'm going to test later to see if the server side rule for automatic replies is 'smart' like OoO where it only replies once per address per 14 hour period.

The risk of a loop from an Out of Office without a rule is small because the Out of Office message is sent only once to each sender. Add a rule to the Out of Office, however, and you might have a problem because the rules, whether added in Out of Office or the Rules Wizard, fire for all messages.

I seem to remember reading on slipstick somewhere (cant' find it now) that server auto-replies function similar to OOO in that they won't reply to every message from a sender but only once every 24 hour period.

In this scenario, because these message settings are organization-wide settings, you must use more than one Active Directory directory service forest. That's just silly right there.
