Create an Office 365 group in the Microsoft 365 admin center

While users can create an Office 365 group from Outlook or other apps, as an admin, you may need to create or delete groups, add or remove members, and customize how they work. The Microsoft 365 admin center is the place to do this.

Create an Office 365 group

1. Select Add a group.

2. On the Choose a group type page, select Office 365, and select Next.

3. On the Basics page, type a name for the group, and, optionally, a description. Select Next.

4. On the Edit settings page, type a unique email address for the group, choose a privacy option and whether you want to add Microsoft Teams, and then select Next.

5. On the Owners choose the name of one or more people who will be designated to manage the group. Anyone who is a group owner will be able to delete email from the Group inbox. Other members won't be able to delete email from the Group inbox. Select Next.

6. After reviewing your settings and making any changes, select Create group.

7. Select Close.

Configure the group

Once the group has been created, you can add members and configure additional settings.

Users can add themselves or request approval, or you can add them now.

1. In the admin center, refresh the page so your new group appears, select Groups > Groups, and then select the group that you want to add members to.

2. Next to Members, select Edit.

3. Select Add members.

4. Select the users you want to add, and then select Save.

5. Select Close three times.

The group will appear in Outlook with members assigned to it.

Send copies of conversations to group members' inboxes

When you use the admin center to create a group, by default users do not get copies of group emails and meeting invitations sent to their inboxes. They'll need to go to the group to see conversations and meetings. You can change this setting in the admin center.

When you turn this setting on, group members will get a copy of group emails and meeting invitations sent to their Outlook Inbox. They can read and delete this copy of the email and not affect anyone else. In the Group inbox, a copy of the email still exists.

Group members can opt out of receiving these emails by choosing to stop following the group in Outlook.

1. In the admin center, go to the Groups > Groups page, and then select the group you want to change.

2. Next to Name, select Edit.

3. Turn Send copies of group conversations and events to group members' inboxes to On if you want members to receive copies of group messages and calendar items in their own inbox.

4. Select Save.

Let people outside the organization email the group

This option is great if you want to have a company email address such as info@contoso.com.

1. Refresh your admin center page so your new group appears.

2. In the admin center groups list, select the group you want to change, and then next to Name, select Edit.

3. Set the Let people outside the organization email the group toggle to On.

4. Select Save.

Who can delete email from the Group Inbox?

The Group owner can delete any emails from the Group Inbox, regardless of whether they were the initial author.

A member can delete an email conversation from the Group Inbox if they initiated it, and only using Outlook on the web (right-click the email, then choose Delete). They can't do it from the Outlook app (Outlook 2016).

When an email is deleted from the group mailbox, it is not deleted from any of the group members' personal mailboxes.
