What is Out of Office (OoO)?

Out of Office (OoO) is a message that replies automatically to any incoming emails.

People use OoO messages when on vacation, sick leave, or taking a leave of absence. Others use it to let people know they will not respond to emails until they return.

To write a good out-of-office message, you include:

• The dates you’ll be gone
• A brief reason for your absence
• Provide contact information of people who they might write to in case of urgent matters.
