Creating and Managing Messaging Policies
Messaging policies allow Teams Administrators to indicate which messaging features team owners and members are allowed to use. For example, you may wish to prevent the deletion of sent messages for a specific group of users by creating and assigning a messaging policy that removes the deletion option for sent messages.
By default, like all Teams policy types, your organization has a Global (Org-wide default) policy assigned to all users. This global policy can be modified, or you can create additional policies to assign them to specific groups and users, leaving the global default policy in place for users to whom custom messaging policies will not apply.
Note
Each user in your organization can only have one messaging policy applied to them at a time. This affects their experience in all teams uniformly and cannot differ per team.
Now, you will look more closely at how to create messaging policies.
