Manage Group membership in the Office 365 admin center

In Office 365, a Group is a shared workspace for conversations, calendar events, and files. As the global administrator, you don't have to be the Group creator, owner, or member to manage Groups.

The Groups dashboard in the Office 365 admin center is where you view and manage all the Groups in your tenant, including Office 365 groups, Security groups, Distribution lists, and Mail-enabled security groups. This article applies to Office 365 groups.

For help creating a group, check out Create an Office 365 group.

Create Dynamic Membership Groups using the Azure Management Portal

Admins can now create Office 365 Groups with rule-based memberships using the Azure Management Portal. Group membership is updated within a minute as users’ properties change.
