Determine if Outlook email attachment is an embedded email or a file

I am opening a PST. Spinning through the folders and emails.

When I hit an email via the MessageInfo item and it has attachments, how do I determine if the attachment is an embedded email or a file?

Basic snipped I am using is below:
For Each messageInfo As MessageInfo In messageInfoCollection
            Dim message As MapiMessage = personalStorage.ExtractMessage(messageInfo)
message.Save("\extracted" & message.Subject & “.msg”)
Next messageInfo

Hi Salemntulsa,

Thank you for writing to Aspose support team.

You can use the following code sample to determine if the attachment to a MapiMessage is another embedded email or not. Please try it at your end and let us know your feedback.

Sample Code:

var message = Aspose.Email.Outlook.MapiMessage.FromFile(str_path);
var attachments = message.Attachments;
foreach (var attachment in attachments)
if (attachment.ObjectData != null && attachment.ObjectData.IsOutlookMessage)
var embeddedMessage = Aspose.Email.Outlook.MapiMessage.FromStream(
new System.IO.MemoryStream(attachment.ObjectData.Data));
