Click on File, then Automatic Replies
This window will appear next that will allow you to set up your Out of Office settings.
-Check the Send automatic replies to turn on the feature
-You can set the time range for how long you want this feature turned on for
-On the Inside My Organization tab, construct your reply message that will be received when you get an email.
-You can also perform the same action for emails that come from Outside My Organization, however unless you are expecting an email from outside the district, we recommend leaving this off so that you don't reply to spam messages.
When you return to work, you can disable the Automatic Replies by going back to File, then clicking the Turn Off button or by simply letting your time range pass as well.
