Microsort Exchange mail has encryption built into it - so for example if I go to my account details settings in Outlook, select my exchange account, click on more settings.. and go to the security tab, there is a checkbox that is ticked called 'Encrypt data between Microsoft Outlook and Microsoft Exchange'. Even though I have that box ticked (I presume it is ticked by default) - Mapiex works fine for me, because it is using the Microsoft Mail technology.
If you are looking to encrypt emails using a technology outside of Microsofts normal mail features - then obviously that is not going to be part of the Mapie API either and you will need to look to create a different interface for your bespoke email solution.
I am not sure what the utility - encryption object is for, my presumption it is a pre-cursor to Credentials Manager and the ability to encrypt work queue data rather than related in any way to encrypting emails.
