What does the default policy do?

The default DLP policy for Teams tracks all the credit card numbers shared internally and externally to the organization. This policy is on by default for all users of the tenant. It does not generate any policy tips for end users but does generate an Alert event and also triggers a low severity email to the admin (added in the policy). Administrator can view the activities and edit the policies details by logging into the Microsoft Purview portal.

Admins can view this policy in the Microsoft Purview portal. Navigate to Data Loss prevention > Policies.

Edit or delete the default policy

To edit the default policy for better performance or to delete it, just use an account with DLP Compliance Management permissions. For more information, see, Permissions.
