Chris - thanks for clarifying. This "feature" has slowed to downloading only one or two emails per attempt. It took the better part of two hours yesterday to download about 9,000 emails. I still have about 3,000 to go. At this rate, I'll be here a while.

The "feature" actually slowed to one email conversation at a time. after about 16 hours at it, I finally imported all 12,700 emails into DPIM. Not ideal, but we got there.
