I have designed a form that will be used over and over in an office. How can I ensure that each time it is filled in, the user saves it under a different name instead of overwriting the original? (I have protected the form itself so that only the fill-ins
can be changed.)
Save the form as a template, and remind everyone to use the File > New command to make a new document based on the template,
not to open and edit the template itself. That's the way Word is supposed to work.
If necessary, store the template in a network folder to which only you (and/or network administrators) have write access.
If you can't do that, then the alternative is to add a macro to the form (which must then be saved as a macro-enabled template or document, *.docm or *.dotm) that runs whenever the form is about to be saved, and forces the name change.
