I am receiving a message "Unable to open that message" when I try to open an attachment with Aspose.Network 3.9.0 eventhough I am able to open the attachement through outlook our other email clients.
I had the same problem with a previous version and upgraded to correct it however it occured again eventhough I delete the message and try others.
Any ideas?
I can give you may email account if needed and test code.
