Opening email files that have attachments in c#.net

Question

Right now when we open up a email file that has been saved, and it has an attachment the attachment is read-only. We need the attachment to be able to be clicked and opened just like it is when you open the saved email from its location.

Currently we have this: foreach (OutlookStorage.Attachment attach in outlookMsg.Attachments) { sHTML += attach.Filename + ", " + attach.Data.Length; }

I am thinking it needs to be something like this: outlookMsg.Attachments.Add();

Thanks for you help.
