When you join a group, you gain access to the group mailbox and a group calendar. If the group is connected to a work or school account using a qualifying Microsoft 365 subscription, you also gain access to a OneNote notebook and team site. Permissions are taken care of automatically so you don't need to worry about missing any meetings or conversations.

Once you've joined a group you'll receive a welcome message that contains important information and links to help you get started. If the group is public, you'll get the message right away. If the group is private, you'll get the welcome message after you've been approved by a group owner.

If you've suddenly started receiving emails from a Group in Outlook, you may be wondering how you got added to that group, and perhaps how you can leave the group. When you were added you should have received a welcome email that tells you about the group, including who added you. It's possible that email may have gone into your junk email or spam folder.

When you locate the welcome message you'll discover who added you, what the group is about, and you'll find a link to leave the group if you'd rather not be a member.

Follow a Group in new Outlook 

After you've become a member of a group, your follow preference will determine how many group emails you'll receive in your personal inbox.

When you follow a group, all the email messages and meeting invitations are sent directly to your inbox. But they’re also stored in your group folder. So don’t worry about accidentally deleting something or creating a rule to move mail from your inbox to a private folder. Delete it from your inbox after reading it and know there’s still a copy safely stored in your searchable group folder; in fact, all the messages since the group began are stored in the group folder. Even if you weren’t a member at the beginning, you’ll get to see the full history once you join.

  1. From the navigation bar select  Groups icon Groups.

  2. On the Group Home tab, select a group card.  

    Tip: Select the entire (or blank space) of the group card to access that group's home. When you select the group name or icons, you'll access different features.

    A group card displays the group name, number of members and has icons for email, files, calendar, and members.

  3. Use the drop-down list to choose your follow preference.The drop down list will show your follow options: follow in inbox, follow only specific emails in inbox, or stop following in inbox.
