NonVisuals don't return .MSG attachments

Question

I use this part of code to retrieve all attachments of an email

foreach (MimeData mime in email.NonVisuals)
{
     mime.Save(System.IO.Path.Combine(myPath, mime.SafeFileName));
}

But if the email has .MSG attachments, they are not saved.

Any ideas to get .MSG attachments?

Thanks.

Without the raw eml data it's hard to tell definitely what the problem is.

My guess is that .msg files are attached as inline elements - they don't have "content-dispostion" header set to "attachment".

Please check if they are available in IMail.Visuals collection (or IMail.Attachments).

Mail.dll uses 4 collections to represent email attachments:

• IMail.Attachments – contains all attachments (includes all other collections).
• IMail.Visuals – visual elements, files that should be displayed to the user ("content-dispostion" header set to "inline" or no "content-dispostion" header).
• IMail.NonVisuals – non visual elements, “real” attachments ("content-dispostion" header set to "attachment").
• IMail.Alternatives – alternative content representations, for example ical appointment.

In most cases using IMail.Attachments is the way to go.
