My guess is that the original main
document has a prespecified link to the data base such that when I open
the
document in Word 2007 the mail merge has already taken place and the
letters
are already completed and ready for me to view/edit. This is what is
currently happening.
Although a typical Mail Merge Main Document would have a data source
attached, for the merge to be performed there would need to be an "AutoOpen"
macro that executed automatically, and that would typically create a new
document containing all your letters. That document would not be linked to
the data source and would not have any { MERGEFIELD } fields in it (although
there may well be other field types. If you modified /every/ June to
September in that document and saved/closed it, I would expect that document
to be the same when you re-opened it.
Which makes me wonder whether this is a "typical mail merge main document".
It might be a document with a more complex VBA macro that does something
else altogether, or it could even be Word document with some .NET/VSTO code
in it. However, f the document is being transformed into a mail merge
"output" document as you open it, it may be hard to discover. The easiest
way to find out is probably to ask someone in your organisation.
However, when you open it, can you see any fields at all, e.g. using Alt-F9
to show field codes rather than results? Or maybe there are some Content
Controls in there. If a merge occurs automatically, maybe you could prevent
that happening by
a. opening a new blank document
b. using Insert->Object->Text from file (sorry, I don't have the precise
option name in front of me) to insert 2Q09cert.doc or .docx. If it's a
traditional document with VBA macros, the macros should not run in that case
and you might be able to see what is going on.
