How to create a Distribution Group in O365 for Exchange Online

Distribution Group: A distribution group, also called a public group, is a collection of two or more people that appears in the shared address book. When an email message is sent to a group, it goes to all members of the group. Using a group, instead of typing individual email addresses, saves time and ensures that everyone is on the same page.

In this task, you will create a distribution group that includes John Snow and Robb Stark. A distribution group can optionally be configured to receive email from external users. This allows you to create a list such as “support,” “sales,” or “inquiries” designed for the public to use.

1.      At the top of the page, click Admin.

2.      Click Exchange.

3.      In the Exchange admin center page, click Groups.
