Does M365 subscription come with a pre-defined set of user groups?

Question

When a new customer buys an M365 license, do they get an Azure Active Directory tenant provisioned for them? If yes, does that come with some pre-defined user groups that dynamically include all users? Is there any documentation that gives more details on these questions?

Answer 1

Yes, every Microsoft 365 tenant comes with Azure AD. As for groups, there are no built-in ones. Depending on the licenses purchased, creating a "All users" group can be done via dynamic membership rules: https://learn.microsoft.com/en-us/azure/active-directory/enterprise-users/groups-create-rule

Here are some examples of the specific rules you can use: https://learn.microsoft.com/en-us/azure/active-directory/enterprise-users/groups-dynamic-membership#other-properties-and-common-rules
