Years ago, I had Outlook at my work set so that Completed Tasks were removed from my Item count list, not visible in my main Task list, but NOT deleted so I could go back and review everything I'd completed in the previous day/month/year/whatever.

I don't know how to set that up again. I want to be able to see how many current tasks I have, with Completed Tasks NOT in that list, but stored elsewhere for later review.

I'm sure it's "do-able" and some will think me an idiot for not figuring it out on my own, but there it is. Help please anyone?
