Inserting Bookmark text into Outlook

[Ed]

I use Word as the default composer in Outlook.

I have a button that will insert into the active document the text of a
certain bookmark found in another Word document.

Here is the essence of the code:

Selection.InsertFile FileName:=MyDocName, Range:=Term2use

In 'regular' Word, the process works just fine, and the text found in
bookmark 'Term2Use' in properly inserted.

But in Outlook, the command results in the entire document "MyDocName.doc"
being inserted as an attachment to the message. Is there any way to get just
the term and not the entire document?
