Automatic replies (formerly Out of office assistant)

This topic shows you how to automatic replies in Outlook Web App using the Automatic Replies tab. Use automatic replies whenever you want to let people who send you email know that you won’t be responding to their messages right away. After automatic replies are turned on, they’ll be sent once to each sender.

If you have a Microsoft Exchange-based email account, for example, a Microsoft Office 365 account, and you use Outlook and Outlook Web App, you can use either one to manage your automatic replies. For information about how to set up automatic replies in Outlook, see Automatically reply to email messages with an Exchange Server account.
