Email Banners in Shared Mailboxes do not have the block / allow sender options. They need it.

We have the "Caution! This message was sent from outside your organization." Banners turned on in our email protection.

In the normal user mailboxes the options to allow / block sender is shown.

In the shared mailboxes the banner is shown but the options are missing.  This needs to be changed.

With as much spam as Sophos Central allows through (wich is daily more and more), we need the option to be able to block the spam at the source.
