Hi,
how to extract attachments from TNEF containers into AttachmentCollection using GetAttachmentsFromTnef method and then treat them like any other attachments ?

Not sure we understood the problem. Please take a look at the following code (found here):

Code:

MailMessage msg = new MailMessage();

msg.LoadMessage(@"C:\Docs\mstnef.eml");

foreach (Attachment attach in msg.Attachments)

{

    if (attach.IsTnef)

    {

        attach.GetAttachmentsFromTnef().SaveAll(@"C:\Temp");

    }

}

This code loads message from file, retrieves all the attachments found in message, every attachment is analyzed and in case if it's TNEF attachment, its content is extracted with GetAttachmentsFromTnef method, so you get attachments collection you can process the way you need.

"(...)However, MailBee allows the developer to extract attachments from TNEF containers into AttachmentCollection using GetAttachmentsFromTnef method and then treat them like any other attachments"

Well, using SaveAll was just an example of what you can do with attachment collection. If you need to process them one by one, you can do it as follows:

Code:

MailMessage msg = new MailMessage();

msg.LoadMessage(@"C:\Docs\mstnef.eml"); 

foreach (Attachment attach in msg.Attachments)

{

    if (attach.IsTnef)

    {

        AttachmentCollection coll = attach.GetAttachmentsFromTnef();

        foreach (Attachment att in coll)

        {

        // e.g.:

        // att.Save(@"C:\Temp\" + att.Filename, true);

        }       

    }

}
