Verify Microsoft 365 Licensing for Default Sensitivity Labels
Understand the subscription requirements and how library-level labeling affects users with different licenses.
Configuring default sensitivity labels in a SharePoint document library typically requires advanced compliance licenses. Because this setting is applied at the library level, any file uploaded or created by a user with access will automatically receive the default label, regardless of that individual user's specific license level.
Log in to the Microsoft 365 admin center and navigate to 'Billing' > 'Your products' to verify if your organization holds Microsoft 365 E5 or an equivalent Microsoft Purview license.
Consult the official Microsoft Purview documentation for the most up-to-date subscription and licensing requirements regarding sensitivity labels.
For definitive answers tailored to your specific tenant mix, open a support request with the Microsoft Purview or Compliance team via the 'Support' tab in the Microsoft 365 admin center.

Frequently Asked Questions
Do all users need an E5 license if a SharePoint library has a default sensitivity label?
No. Because the default sensitivity label is configured at the library level, files created or uploaded by any user with access to the library will inherit the default label, even if those specific users do not individually hold an E5 license. However, the organization must have the appropriate licenses to configure the feature.
Where do I configure sensitivity labels for SharePoint?
Sensitivity labels are configured and managed within the Microsoft Purview compliance portal. Administrators must create the labels, publish them via label policies, and then apply them to the target SharePoint sites or document libraries.
What happens if a user uploads a file that already has a sensitivity label?
If a user uploads a document that already has a sensitivity label applied manually, the existing label is typically retained and will not be overwritten by the SharePoint document library's default label, unless the existing label has a lower priority.
Can I use default sensitivity labels without a Microsoft Purview license?
Generally, no. Advanced features like setting default sensitivity labels for SharePoint document libraries require specific enterprise licenses, such as Microsoft 365 E5 or an appropriate Microsoft Purview add-on.
