Import Profile Failed. Any tools to extract calendar data from profile? I wish they had a) kept the ability to look at prior events in the most recent version of Thunderbird b) kept the option to export calendar as csv file. But here we are. Is there any sort of stand-alone utility or any other way for me to get at my calendar data? I installed an older version of Thunderbird, which has no problem with the rest of the profile, but chokes on the calendar.
