Whether you’re going to be out of the office for a couple of hours or for an extended time period, it’s a good practice to turn on Automatic Replies. This will let others know you’re out of the office and can’t be reached.
To turn on Automatic Replies from the Home view of your email, Click the File tab.
Next Click Automatic Replies.
When the Automatic Replies window opens, Click Send Automatic replies. Click Only send during this time range to specify when you want Automatic Replies to start and end. You can also tailor your reply to those inside DHS and to those outside of DHS. The message should include when you’re leaving/returning to work as well as who and how to contact others in your absence. Click OK when finished.
The home view of your email now displays a message that Automatic Replies are being sent and a button that allows you to turn them off if you wish.
