Swimming in Exchange Calendar Duplicates

I don’t know what is doing it. Entourage, the many synchronizer, but I’ve got 1100 duplicate calendar entries which is depressing since I deleted 500 last week. Time to buy a deduplicator. There don’t seem to be any for Entourage that don’t take weeks to run, so I’m having to do this with Outlook under Parallels. The google:”outlook duplicates” search revelas Mapilab and “Sperry”:http://sperrysoftware.com both make these. I’ve use Mapilab and it costs a ridiculous $24 to get something that shouldn’t happen. Sigh.
