@AStelzner,

Please try using following example on your end to access the cloud attachment that appear as Linked resource.

        public static void TestAttachment()
        {
            String path = @"C:\Users\mudas\Downloads\Test Mail mit Cloud Attachment (1)\";
            MailMessage msg = MailMessage.Load(path+ "Test Mail mit Cloud Attachment.msg");

            for (int i = 0; i < msg.Attachments.Count; i++)
            {
                Attachment attachment = msg.Attachments[i];
                // The above attachment is a file, the size of this file after extraction is not same as the one attached to the parent EML or MSG file.
            }

            for (int i = 0; i < msg.LinkedResources.Count; i++)
            {
                LinkedResource linkedResource = msg.LinkedResources[i];
                // The above linkedResource  is a file, the size of this file after extraction is not same as the one attached to the parent EML or MSG file.
                linkedResource.Save(path + linkedResource.ContentType.Name);   
            }
        }
