Search on the name of your list, check the box next to the name and then click Edit in the menu bar.

Note: to subsequently edit your list, click on the Office 365 pop out menu icon, click on People. Add all the people who you want to be in the list in the same way.Once you have clicked on the person's name they will be added to the list.If the person is not already one of your contacts, you can choose to search the University's directory In the Add members box, start typing the name of someone you want to add to the list.Think privacy.when naming your contact group, think about making sure it has a name that is obviously different from any other contact lists or resource accounts you use. This is essential to avoid inadvertently sending information to the wrong person / group. The most important thing is that the first few letters are not the same as any other email addresses or groups you use. For example, rather than having the groups “Childhood Yr1” and “Childhood Yr2”, perhaps call them “1st Year Childhood” and “2nd Year Childhood”, so that the first few letters are different. The autocomplete feature in Outlook can be very helpful but only if it autocompletes with the correct address.

You can create a group to store a list of people you want to send email to.
