Can I freeze all cookie dough? How far in advance can I make it?
All baking dough does well in the freezer for a few days. But I'd suggest not thinking of meringue cookie mixture as cookie dough... it's an entirely different animal. I think of dough as anything with lots of flour and a decent amount of fat and moisture in it. You can't freeze anything with whipped egg whites and expect it to survive. You can't even leave whipped egg whites to settle on the counter for very long before they start to loose the air bubbles you've worked so hard to incorporate.
