I'm developing an Office 365 Outlook add-in and I would like to save any mail in .msg file.
So far, I read this reference : https://dev.outlook.com/reference/add-ins/ and didn't find anything that allow me to create .msg file from a mail, in Javascript.
Is it possible to generate a .msg file from javascript?
I use a ASP.NET MVC Web Server (which will be on Azure later) in C# for executing the add-in, so I can use any C# package. I also can't pay for any plugin or library.
