You have a Microsoft 365 tenant that uses Microsoft Purview Information Protection.

You create a sensitivity label named Sensitivity1 and configure Sensitivity1 to encrypt files and emails.

You publish Sensitivity1.

You discover that users are NOT prompted to apply Sensitivity1 to their files and email.

You need to ensure that the users must apply Sensitivity1 to their files and email before saving the files or sending the emails. The solution must meet the following requirements:

• Prevent users from removing the label from the files and emails.

• Minimize administrative effort
