Hi @Glenn Maxwell,
Thank you for posting in this community.
We need to manage this SharePoint site in SharePoint Admin Center. So please contact your global administrator or SharePoint administrator for the following:
- Navigate to your SharePoint admin center, click on “Active Sites” and locate the SharePoint site associated with your 365 group. The URL for the SharePoint admin center is usually:
https:// yourtenantName-admin.sharepoint.com/
.
- Select this SharePoint Site and click the “Membership” button at the top. In the popup panel you can see all the members of the site and you can delete the members here. Please remember that you must keep a primary administrator in “site admins” otherwise no one will be able to access the site (the site will be inaccessible).
