Lost calendar entries Rated 3 out of 5 stars

This would be exactly what I need if I could get it to work correctly, but I'm now rather fearful because after finally figuring out how to set it up (perhaps incorrectly, I don't know), it deleted a whole bunch of Lightning calendar entries on 1 of the 2 computers I was trying to sync, as previously described by ikpetrof. Unfortunately, there is not much documentation on setting this up and how it is supposed to work. It actually took me some time to figure out that it was up to me to add the requisite imap folder and how to do that.

This review is for a previous version of the add-on (2.0.1).
