Hello Armando,
Attached is a new Outlook VBO prototype for you to experiement with and expand as you wish. It does not use Mapie, it instead uses an Outlook dll api. There is a Save Item action within it.
NOW FOR SOME WARNINGS: First: I provide this to you 'as is' - it is an early prototype and therefore is not supported by us or our product team (but i know it has been used in at least one client project). If you find any issues with using it please feel free to let us know here, but do not raise it with our support team who will not help you. Second: this VBO requires a Microsoft.Office.Interop.Outlook.dll file that is not installed by default with many Office installations so you may need to download and install 'Office Primary Interop Assemblies' from Microsoft. Also, there is an External Reference to that dll path in the code options of the VBO which you would need to amend to point to where it gets installed on your computer.
Good luck,
Den
