The usual way is to use the same datasource for a separate Envelope type
mailmerge.. Can you add an envelope to the main document and insert the
merge fields into the envelope as well as into the letter part of the
document and then execute the merge?

It is not really possible to use the merged letters themselves as a
datasource. It is probably possible however to write a macro to extract the
addresses into a separate document that could be used as a datasource.

I can't merge the name and addresses from letters in a mass mailing into
labels. The data base came from a different program so I can't use that.
Is
there not a way to merge from the letters which are already created?
Thanks,
