DocumentViewer for msg file does not recognize attachment type if the attachment is another msg file
Problem reported by Daniel - 6/16/2021 at 3:22 AM
I am evaluating the product for a project and I have ran into a small issue and I was wondering if anyone knows a way around it. Within the project I am developing for, there are a number of msg files than have msg files as attachments. When I try to open the attachment in DocumentViewer I get a message saying the file does not have an extension nor is the type specified so it cannot open it. 

I tested this with a DotNet Core app and also with the the online viewer https://demos.gleamtech.com/documentultimate/AspNetWebFormsCS/#DocumentViewer/Overview.aspx.

For the demos.gleamtech, I tested it by creating an email in Outlook and attaching a previously saved msg file, then saved that email as msg. I then opened it in DocumentViewer. You can see the attachment in the list but you cannot view it. 

Does anyone know of a workaround for this issue?
