Question details
The user needs to configure a Data Loss Prevention (DLP) rule requiring approval before sending emails containing sensitive data like credit or debit card numbers, and is comparing licensing options such as Business Premium, DLP add-ons, and Microsoft Entra ID P1.
- Product
- Microsoft Purview
- Device & OS
- not provided
- Scenario
- Setting up an email approval workflow to prevent the unauthorized transmission of sensitive financial data.
- Observed behavior
- The user is seeking clarification on which specific Microsoft 365 licensing tier is required to support advanced DLP rules and approval workflows.
Before configuring DLP policies, ensure you have global administrator or compliance administrator permissions in your Microsoft 365 tenant to view and assign appropriate licenses.
Determine the Correct Microsoft 365 License for Your DLP Workflow
Identify which Microsoft 365 or Purview license provides the required capabilities for advanced email approval workflows involving sensitive information.
Microsoft Entra ID P1 focuses strictly on identity and access management and does not include Data Loss Prevention (DLP) capabilities.
While Microsoft 365 Business Premium includes basic DLP features, advanced compliance capabilities like routing emails for manager approval based on sensitive content typically require higher-tier enterprise licenses.
Recognize that Microsoft Entra ID P1 will not fulfill your requirement, as it does not provide any native Purview Data Loss Prevention capabilities.
Log in to the Microsoft Purview compliance portal to check if the basic DLP policies included with Microsoft 365 Business Premium meet your needs. Business premium covers standard data protection but may lack complex approval routing features.
For advanced compliance workflows requiring approvals before sending sensitive data, procure and assign a Microsoft 365 E5 license or purchase a Microsoft E5 Compliance add-on for your users.
After securing the appropriate E5 or Compliance add-on license, verify within the Exchange Admin Center and Purview portal that your service and tenant configurations support the intended approval workflow before enforcing the policy.
