You need to implement a solution to meet the Microsoft Teams requirements for the compliance department. What should you do first?

An org-wide team is generally for organizations with fewer than 10,000 members and automatically adds all users, which might not be suitable for a specific department's compliance requirements.

A universal security group is a foundational building block for managing access and permissions across Microsoft 365 services, including Teams. By placing all compliance department users into such a group, you can then use this group to control access to specific Teams, channels, or apply policies, making it a logical first step for managing a department's Teams requirements centrally.

An Office 365 group (now Microsoft 365 group) is also a good option, as it forms the basis for a Microsoft Team, but a universal security group can be used more broadly for policy assignments and access control before or in conjunction with team creation.

Assigning the Teams Communications Support Engineer role provides administrative permissions related to Teams voice features, which is likely not the initial or primary requirement for all compliance department users.
