Rated 2 out of 5 stars

This didn't work when I tried to add my existing remote calendars, because the section that tries to validate them always fails, even though I have all my passwords for those accounts. Perhaps it's not meant to work with email aliases?

This review is for a previous version of the add-on (72.1).
