2.3.1.1 Ensure 'Accounts: Block Microsoft accounts' is set to 'Blocked'

Information

This policy setting prevents users from adding new Microsoft accounts on this computer.

The recommended state for this setting is: Blocked:.

The value of Enabled (users can't add Microsoft accounts) or Users can't add or log on with Microsoft accounts is considered compliant for this recommendation when using a Custom Profile.

Rationale:

Organizations that want to effectively implement identity management policies and maintain firm control of what accounts are used to log onto their computers will probably want to block Microsoft accounts. Organizations may also need to block Microsoft accounts in order to meet the requirements of compliance standards that apply to their information systems.

Impact:

Users will not be able to log onto the computer with their Microsoft account.
