To assure the best experience for end users, Teams provides IT organizations with a variety of governance controls. If you require strict controls on how teams are named and classified, or whether guests can be added as team members, you can configure each of these areas in Azure Active Directory (Azure AD).
Team Naming: A group naming policy is used to enforce a consistent naming strategy for Office 365 groups created by users in your organization. The best practice for this is to conduct interactive on boarding with the early adopter project team and allow them to select their own name. This will give you insight into how employees think about their work and will be essential in creating a larger scale naming convention at a later time. You can use Prefix-suffix naming conventions which will allow to add or append fixed strings or supported user attributes to the teams name. Blocked words can avoid (intentional or unintentional) misuse of teams. Configure via Azure Active Directory Module for Windows Power Shell. Find details on licensing and configuration here.
