Manage Microsoft 365 groups
This article applies to both Microsoft 365 Enterprise and Office 365 Enterprise.
You can manage Microsoft 365 groups in several different ways, depending on your configuration. You can manage user accounts in the Microsoft 365 admin center, PowerShell, in Active Directory Domain Services (AD DS), or in the Microsoft Entra admin center.
Plan for where and how you will manage your groups
Where and how you can manage your user accounts depends on the identity model you want to use for your Microsoft 365. The two overall models are cloud-only and hybrid.
You create and manage groups with:
AD DS groups are synchronized with Microsoft 365 from AD DS, so you must use on-premises AD DS tools to manage these groups.
You can also create and manage Microsoft Entra groups that are separate from AD DS groups but can contain users and groups from AD DS. In this case, you can use:
Allow users to create and manage their own groups
Microsoft Entra ID allows groups that can be managed by group owners instead of IT administrators. Known as self-service group management, this feature allows group owners who are not assigned an administrative role to create and manage security groups.
Users can request membership in a security group and that request goes to the group owner, rather than an IT administrator. This allows the day-to-day control of group membership to be delegated to team, project, or business owners who understand the business use for the group and can manage its membership.
Self-service group management is available only for Microsoft Entra security and Microsoft 365 groups. It is not available for mail-enabled groups, distribution lists, or any group that has been synchronized from AD DS.
For more information, see the instructions to configure a Microsoft Entra group for self-service management.
Set up dynamic group membership
Microsoft Entra ID supports configuring a series of rules that automatically add or remove user accounts as members of a Microsoft Entra group. This is known as dynamic group membership. The rules are based on user account attributes, such as Department or Country.
Here's how the rules are applied:
- If a new user account matches all the rules for the group, it becomes a member.
- If a user account isn't a member of the group, but its attributes change so that it matches all the rules for the group, it becomes a member of that group.
- If a user account doesn't match all the rules for the group, it isn't added to the group.
- If a user account is a member of the group, but its attributes change so that it no longer matches all the rules for the group, it is removed as a member of the group.
To use dynamic membership, you must first determine the sets of groups that have a common set of user account attributes. For example, all members of the Sales department should be in the Sales Microsoft Entra group, based on the user account attribute Department set to "Sales".
Set up automatic licensing
You can configure security groups in Microsoft Entra ID to automatically assign licenses from a set of subscriptions to all the members of the group. This is known as group-based licensing. If a user account is added to or removed from the group, the licenses for the group's subscriptions will be automatically assigned or unassigned from the user account.
For Microsoft 365 Enterprise, you'll configure Microsoft Entra security groups to assign the appropriate Microsoft 365 Enterprise license.
Make sure you have enough licenses for all the group members. If you run out of licenses, new users won't be assigned licenses until licenses become available.
You should not configure group-based licensing for groups that contain Azure business to business (B2B) accounts.
