I have tried several solutions out there to enable Drag & Drop files in CRM.
Most of them work really well with most file types.
But for some reason, .msg files seem to be problematic. With some solutions, an error gets thrown when we drag & drop a .msg file. With some solutions, the .msg files gets converted to a .txt file.
Here are the ones we tried:

Any ideas why this specific file type would not be supported?
