Question details

The user needs to push PC configurations after upgrading users from Microsoft 365 F1 to Business Premium but finds the Device Configuration options are unavailable.

Product: Microsoft 365 Business Premium
Device & OS: not provided
Scenario: Upgrading user licenses from F1 to Business Premium and attempting to push security configurations to PCs.
Observed behavior: The Device Configuration options are unavailable or missing from the expected admin interface.

Before you start

Ensure you have global administrator or security administrator privileges in your Microsoft 365 tenant before verifying license assignments and portal access.

Solution 1Recommended

Access Device Configurations via the Microsoft Defender Portal

Microsoft Defender features are licensed and supported separately from the core Microsoft 365 admin center, requiring administrators to use the dedicated security portal for configuration.

When moving users from Microsoft 365 F1 to Business Premium, the endpoint security and configuration policies shift toward Microsoft Defender for Business (or Endpoint).

Because Defender is licensed separately and operates as a standalone security suite within the Microsoft ecosystem, standard device configuration menus in the basic admin center may appear unavailable or point elsewhere.

Verify license assignment

Check your Microsoft 365 admin center under Billing > Licenses to ensure the Business Premium licenses are fully applied to the affected users.

Navigate to the Defender Portal

Log in to the Microsoft Defender Security Center (security.microsoft.com) using your administrator credentials, rather than using the standard Microsoft 365 admin center.

Locate endpoint settings

In the navigation pane, go to Settings > Endpoints to configure device discovery and push your required PC configurations.

Consult the Defender community

If options are still hidden, post your specific tenant scenario in the Microsoft Defender for Endpoint tech community forums for specialized support.

Review Documentation: Always review Microsoft's official device discovery documentation to ensure your network properly supports Defender configuration deployments.
