C# Cloning Objects that implement neither IClonable or ISerializable

Hi all,

I've tried everything I can think of and cannot figure this out. Basically, I'm making an Outlook 2010 Add-In that makes adjustments to incoming HTML formatted emails for the purposes of making them more Accessible to visually-impaired users (visually impaired users in particular.)

Everything works fine, except that when my Add-In runs, it actually attempts to modify the original email no matter what I try, which Exchange connected Outlook doesn't like at all and rejects. What I want to do is display my modified email message with all of the goodies (reply, reply-all, BCC, etc., just like you would normally use Outlook) without modifying the original message...that is, I only want to display my modified message, not modify the stored message or add a new message.

Such as:

if (selObject is Outlook.MailItem)
  {
      Outlook.MailItem mailItem = (selObject as Outlook.MailItem);
      Outlook.MailItem accessible_mail_item = mailItem;
      ...rest of my code...
      accessible_mail_item.Display(false);
  }

The problem I have is, "accessible_mail_item" is not a copy of "mailItem"...it's a pointer to it. How can I make a copy/clone of this non-Serializable/Clonable Object? I've tried various "Deep Clone" functions out there, but they all give me the same errors about "not being serializable" or whatever.

Any help will be much appreciated!!!!!!!!

Thanks!
