Using New Outlook on Windows for professional communication and productivity
Yes — a member can be removed from a Microsoft Group, and a member can also leave it.
A Microsoft Group gives members access to the group mailbox and group calendar. If the group is connected to a work or school account using a qualifying Microsoft 365 subscription, members can also get access to a OneNote notebook and team site.
If the email is legitimate, the welcome message normally tells who added the member and includes a link to leave the group. That message may also sometimes be found in Junk or Spam.
A safer path than clicking links in the email is to sign in directly to Outlook on the web or new Outlook and leave the group there:
- Select Groups from the navigation bar.
- Select the group.
- Open Group Settings.
- Select Leave Group.
For Outlook.com, the steps are:
- Select the group.
- Select the group name to open the group card.
- Go to the Member tab.
- Select the X next to the account to remove it from the group.
Important: if the account is the last group owner and leaves, the other members are notified and the group’s data and content are deleted in 30 days.
The provided material does not state that other group members can access the local system. It only states that group membership provides access to group resources such as the group mailbox, calendar, and in some cases a OneNote notebook and team site.
