If you open the existing merge document, then use Save As to save it under a
different name, you should be able to change the merge document type to
directory (e.g. using the Mailmerge toolbar) without disconnecting the data
source, in which case you do not need to know what the data source is,
although it obviously still needs to be there.
Other ways to discover the name of the data source (some may not work in
Word 2002 and may even crash it):
a. drag Tools|Customize|category All Commands|command MailMergeHelper to a
toolbar and use it
b. open the VBA editor and execute the following command in the Immediate
pane
print ActiveDocument.MailMerge.DataSource.Name
c. use File|Save As to save your document as a Web page, then open the HTML
file as a text file and look for the block of mailmerge-related information
that should be near the top.
d. Look in Word Help|About|"System Info..."|"Office 2003
Applications"|"Microsoft Office Word 2003"|"Mail Merge" (this can be slow,
though.)
