2003 to 2007 Out of Office Assistant
If you're going on vacation, you can use the Microsoft Office Outlook 2003 and Microsoft Exchange Server 2003 Out of Office Assistant to send automatic replies to your coworkers with a message of your choice. However, most out-of-office replies are limited to internal contacts only.
The improved Out of Office Assistant in Microsoft Exchange Server 2007 enables Outlook 2003 and Microsoft Office Outlook 2007 clients to send separate replies to internal and external contacts. You can also schedule when your out-of-office replies turn on and off. That way, you won't forget to turn them on as you're leaving, and your coworkers won't have to remind you to turn them off after you return.
To use the improved Out of Office Assistant, click the Tools menu, and then click Out of Office Assistant.
