You cannot mailmerge to a protected document. If you execute the mailmerge
to a new document, you could run a macro over that document that separated
it into individual files and protected each of them. After all, it is the
result of the mailmerge that should be the issue, not the source.

I have a main document that needs to print for each id numbers filed in an
Excel Spreadsheet. I'm using mail merge but the problem is that due to
regulatory requirements I need to protect the main document during the
mail
merge but if I do so in Word 2002 (MS Office XP Pro) the mail merge
function
is not allowed. How can I perform this mail merge process maintaining
protected the main document. Is there is a waork around in Word? Is the
new
Word 2003 have this capability? Is there is another MS or third party
software that provide this capabilities?
