New Outlook/OWA Allows you to see Private Items not visible in Outlook Classic

When a user has full access to a mailbox that user can see items that are marked private in New Outlook/OWA

Is there any way to prevent this in New Outlook/OWA when a user has full access?

    No—currently in New Outlook/OWA, private items are visible to users with full mailbox access. Unlike classic Outlook, the “private” flag isn’t enforced. The only workaround is to restrict or remove full access delegation until Microsoft updates this behavior.
