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.
