Javax mail extract msg attachment

Question

I have a mail class using javax mail and I’m trying to save an msg attachment. When I send an msg attachment using outlook 2016, it seems that outlook sends it as an elm file. I can read it fine but when I try to open the file with outlook it complains that the email is locked.

Has anyone experienced this? Why does outlook send the file as eml? I can open it in a text editor but not in outlook.
