I am using c# and word interop to open a mailmerge document fill it in and
then display it to the user. Once i display it the c# app has nothing more to
do with the word document. The user can edit it as needed and then save it as
a pdf and that is fine.

The issue is I would like to set the default path for the document and it
could be a network drive or sharepoint and will change every time also it
will never be where the original document was opened.
