In the above document the resource forest scenario is an example of when you would want to associate a mailbox with an external account. In a resource forest scenario, user objects in the Exchange forest have mailboxes, but the user objects are disabled for logon. These disabled user accounts in the Exchange forest are associated with enabled user objects in the external accounts forest.
Resolution
It is necessary for an user account to be active for restoring individual items. This is by design.
Enable the linked user accounts and run the restore.
