Well, I know the Search function has been turned off for the OT archives. Just too time and resource consuming. No idea if that's connected, but it wouldn't totally surprise me.I'm not sure, but I'd guess that you can bookmark a still active thread in OT and have it continue to work even after the thread goes to archive because you've then set a Search point on it for your account. Bookmarking already archived threads probably doesn't work because no Search criteria are defined for the OT archived threads and, since it's already in the archive, it's too late to set one for yourself.
