You can remove members of the cloud account type from your resource directory.
Prerequisites
If a member is a delegated administrator account of a trusted service, the member cannot be directly removed from your resource directory. You must remove the delegated administrator account for the trusted service first. For more information, see Remove a delegated administrator account.
Background information
In a resource directory, members of the resource account type are resource containers that are created by using the management account of the resource directory. You cannot remove such members from the resource directory. For security purposes, you can use these members only within the resource directory.
