Configure Account Restrictions via Microsoft Intune

Use Microsoft Intune device configuration profiles to restrict the addition of non-corporate Microsoft accounts.

This restriction cannot be applied through standard Microsoft 365 admin center settings. It requires device management policies orchestrated through Microsoft Intune and Entra ID (Azure AD).

Access the Intune Admin Center

Create a Configuration Profile

Navigate to 'Devices' > 'Configuration profiles' and click on 'Create profile'.

Select Platform and Profile Type

Choose the appropriate platform (such as Windows 10 and later) and select 'Settings catalog' as the profile type, then click 'Create'.

Configure Account Settings

In the Settings picker, search for 'Accounts'. Select the setting 'Block Microsoft accounts' and configure it to prevent users from adding non-Azure AD accounts.

Assign and Save

Proceed to the Assignments tab, assign the profile to the targeted device or user groups, review the settings, and click 'Save'.

Configure Account Restrictions via Microsoft Intune

Additional Support: Because policy applications can vary based on your specific tenant setup and device enrollment types, complex configurations should be discussed in the dedicated Microsoft Intune Q&A forums.

Frequently Asked Questions

Can I block personal accounts directly from the Microsoft 365 admin center?

No, restricting personal accounts at the operating system or application level requires dedicated device management and identity policies, typically configured through Microsoft Intune or Microsoft Entra ID.

Will blocking personal accounts remove existing personal accounts on a device?

Depending on the specific Intune configuration and OS platform, applying the 'Block Microsoft accounts' policy prevents new accounts from being added. Existing personal accounts may need to be manually removed or targeted with a specific script.

What licenses do I need to use Intune for these account policies?

To configure and deploy these policies, your organization requires Microsoft Intune licensing, which is included in Microsoft 365 E3/E5, Business Premium, or Enterprise Mobility + Security (EMS) plans.
