Hi all,
i still working on a transportAgent which is able to insert a graphic as attachment to all outgoing Tnef mails.
I include this attachment with following code:
But in this case, line 2 gives me an error:
Error 1 Property or indexer 'Microsoft.Exchange.Data.Transport.Email.Attachment.AttachmentType' cannot be assigned to -- it is read only
My Question is: How is it possible to change this attribute or is there another way to put headers like Content-Disposition?
