Sophos Outlook Addin (Office 2019)

Hi all,

We currently use the Sophos Outlook add-in to help our end users with quickly setting emails as confidential which then gets encrypted via mail rules looking for that confidential setting.

The problem is this plugin does not install with Office 2019 and we will soon be upgrading.

Does anyone know what VBA code I could use to add a custom button to the ribbon to do the same job ( enable / disable the confidential setting)?
