OWA—Creating an email group
In OWA, an email group is called a Distribution List. In this tutorial, we will create a distribution list and add some email addresses to it.

First click Contacts on the left side of OWA.

Now select the drop down next to New and choose Group.

Now, you can name your group, type in the email address of someone, and click add to group. You can add multiple email addresses at a time if you separate them with a semi-colon. Email addresses may also be copied into this field from Excel; just select add to group and all the addresses will be added at once.

When you have finished adding people to the group, you will click Save and Close.
Your group is now created and you can send a message to that group without having to type all the members of the group. You can go back and edit your group anytime you like.
