How Do I Set Up an Out-Of-Office Email Auto Reply in Office 365?

Before You Begin

Students and faculty/staff members who use Office 365 will be able to set up an automatic reply in the Office 365 website to send a customized response to people who email you while you are unavailable. This is intended for extended times when you can’t get to your email, such as when you are on vacation.

To set up an automatic reply in Office 365, do the following:

  1. Go to and login with your ULID and password.

  2. Click the [Outlook] tile to open Outlook Online.

  3. Click the [Settings Icon] > [View All Outlook Settings].

  4. Select [Automatic replies] and click the switch to “On” for [Turn on Automatic Replies]

  5. Put a check mark in the box labeled Send replies only during this time period.

    • Specify a time frame for your automatic reply by choosing appropriate start and end dates and times.
  6. Enter a message in the box labeled Send a reply once to each sender inside my organization with the following message.

    • Example: “Please contact Jon Smith at 8-0000 until I return on Oct. 1. Thank you.”

    • If you have used the automatic reply option in the past, your last message will appear in this field.

    • You may copy and paste the same message from the box above or you may send a unique message to those who email you from an off-campus email address.

  7. When you are done, click [Save].
