The Out-of-Office Message is an effective way to alert people who send you email messages that you may not respond immediately. Within the SPU campus Microsoft Exchange system you can set your out-of-office reply from within Outlook 2003/2007 and from Webmail.
The Out-of-Office reply is sent to the "from" address of any on- or off-campus sender.

Some off-campus distribution lists don't handle out-of-office messages in the same manner. The list owners sometimes prefer that you unsubscribe to a specific list to avoid unwanted out-of-office messages from being sent to the entire list, or to list posters. Check with the list manager for assistance with this problem.
Exchange keeps track of who has received your out-of-office reply and doesn't keep sending the message if you've already seen it.
