Sue had good information. Only forwarding is available in Outlook Express. I verified that from quoting Microsoft's website, "The Out Of Office Assistant is not available in Outlook Express. You may be able to duplicate its functionality by applying message rules."
The site continues, "The Out of Office Assistant is a feature of Microsoft Outlook that enables you to automatically reply to e-mail messages from people who send you mail when you are not available. Outlook Express does not have this functionality. To simulate the functionality of an Out of Office Assistant in Outlook Express you must first create an out of office message, and then an out of office rule. Additionally, it is important to remember that this function only works while Outlook Express is running and logged on to the e-mail server."

Good luck with email issues. Such a pain!
