Question details

The user needs to configure email retention policies in Microsoft Purview but is blocked by a prompt stating that Adaptive Protection is required, raising questions about licensing compatibility.

Product: Microsoft Purview / Microsoft 365
Device & OS: not provided
Scenario: Configuring email retention policies and advanced security features within the Microsoft Purview compliance portal.
Observed behavior: The Purview portal restricts access and indicates that Adaptive Protection must be enabled, which fails or remains unavailable because affected users have mixed license types, primarily A1 instead of the required A5/E5.

Before you start

Ensure you are logged into the Microsoft 365 admin center with Global Administrator or Compliance Administrator privileges before verifying or modifying user licenses.

Solution 1Recommended

Verify and Assign Appropriate A5 or E5 Licenses

Adaptive Protection is an advanced compliance feature that specifically requires premium licensing. You must ensure affected users have an A5 or E5 license rather than an A1 license.

Microsoft's advanced security and compliance features, including Adaptive Protection, are not included in baseline educational or enterprise licenses (like A1 or E1). To utilize dynamic retention policies, users targeted by these policies must be assigned the correct premium tier license.

Access the Admin Center

Log in to the Microsoft 365 admin center and navigate to the 'Users' menu on the left sidebar, then select 'Active users'.

Select the Target User

Search for and click on the user who needs the retention policy applied. A properties panel will slide out on the right side of the screen.

Check Licenses and Apps

Click on the 'Licenses and apps' tab. Verify whether the user has a 'Microsoft 365 A5' or 'Microsoft 365 E5' license assigned. If they only have an A1 license, you must acquire and assign the higher-tier license to enable Adaptive Protection.

License Propagation Time: After assigning a new A5 or E5 license, it may take up to 24 hours for the licensing status to sync with the Microsoft Purview portal.

Solution 2

Check Feature Availability in Microsoft Purview

Once proper licenses are assigned, you must verify that the Adaptive Protection feature is turned on in your compliance settings.

Solution 3

Open a Microsoft 365 Support Request

If users have the correct A5/E5 licenses assigned but the Purview portal still blocks access to retention policies, backend synchronization or sales provisioning issues may be at fault.

Frequently Asked Questions

Why does Microsoft Purview say Adaptive Protection is required for my retention policy?

Microsoft Purview integrates Adaptive Protection to dynamically adjust data loss prevention (DLP) and retention policies based on an individual user's risk level. If you are configuring a policy that relies on this dynamic risk profiling or machine learning, the system will prompt you to enable the feature first.

Can I use Adaptive Protection with a Microsoft 365 A1 license?

No. Adaptive Protection is considered an advanced compliance and security feature. It strictly requires Microsoft 365 E5, A5, or an equivalent advanced compliance add-on license. Standard A1 and E1 licenses do not support this capability.

Do basic retention policies always require an E5 or A5 license?

Not necessarily. Basic, manual retention policies can often be applied with standard licenses (like E3 or A3). However, automated retention policies that automatically apply labels based on sensitive information types, machine learning, or Adaptive Protection specifically require higher-tier E5 or A5 licenses.
