Thanks for the update. There is currently no ‘fully-featured’ version of this applet available. The applets on the CoolSolutions web site are examples of the kind of functionality possible with Formativ.
We are constantly updating and adding applets to our ‘Business Solutions Pack’ collection of applets, which represent complete, supported solutions. The ‘save message and attachments’ applet is not currently part of this collection. We may well update this applet to a sufficient level where it would be included. I’m confident such an upgrade would include the functionality you require.
In the meantime, depending on the resources you have available, you might be able to update the applet yourself to add the required functionality. Alternatively, we offer consulting services. Please email firstname.lastname@example.org if you are interested in this option.
I hope this helps.
