Information
Users who are set as subscription owners are able to make administrative changes to the subscriptions and move them into and out of Microsoft Entra ID.
Rationale:
Permissions to move subscriptions in and out of Microsoft Entra ID directory must only be given to appropriate administrative personnel. A subscription that is moved into an Microsoft Entra ID directory may be within a folder to which other users have elevated permissions. This prevents loss of data or unapproved changes of the objects within by potential bad actors.
Impact:
Subscriptions will need to have these settings turned off to be moved.
