Extracting Bitmap-Attachments from Outlook-Msg fails


Iam using Aspose.Network.dll to extract outlook attachments. This works fine for Mails without bitmap as attachments. When I try to extract bitmap-attachments Iam getting a wrong file back.
I have attached a sample project to reproduce this issue. Their are 2 outlook messages withoutBitmap.msg and withBitmap.msg at “applicationpath\mails”. If you start the application, select one of the two files from the listbox and press the GetAttachment-Button. Do the same with the other file and compare the results.

You will need to add Aspose.Network.dll to "applicationpath\lib"

Could you please tell why this happens?

Many thanks in advance
