Overview
The Microsoft "MyGroups" functionality provides web access to manage group membership in Microsoft 365 cloud groups. These cloud groups are used to provide access to Microsoft 365 Groups, Teams, SharePoint Storage sites and more.
Go to the Microsoft "My Groups" web page at https://myaccount.microsoft.com/groups. Click on the "Groups I own" menu item.
Filter the groups by the name if needed. In this example the "Storage" name filter is used. Click on the group you would like to edit.
Click on the "Members" tab to view the current membership.
To add a member, click on "Add".
Enter an email address for the new member and select them from the search drop down.
You can add multiple members at a time. Once, the new members are listed, click on the Add button to add them to the group. It is also possible to add other Owners to the group here as well.
To remove an individual member, click on the "Remove" link to the right on the member row.
To remove multiple members, click on the left side select box for all the members to remove. Then select the "Remove Members" link.
