Open Outlook for Mac and navigate to Tools > Automatic Replies.




In the Automatic Replies window, select the email account for which you want to set up automatic replies (if you have more than one), then click the "Send Automatic Replies" button.

Set the start and end time for the automatic replies, and compose your message. Otherwise, the message will be sent starting now, and continue until you manually turn off. 


To send a different message to people outside your organization, click on "Message for outside your organization". A new box will appear, allowing you to customize the message for external contacts not sending from @pgst.nsn.us.


Once you've configured the time frames and messages, click the red button at the top right to save and queue the automatic reply. If you did not set a time and date, it will be active now. 



When your automatic reply is enabled, a notification will appear on the main screen of your email. You will see a similar one if you're using the Outlook for Web at https://outlook.office.com/mail/
