How do I find old calendar data ? and change calendar location
During a recent auto update to TBird , I lost all of my Lightning ( calendar) data. The calendar add-on was not working correctly so I reinstalled Lightning.. But before or after I could not find the old appointments in a calendar data file to load into the updated calendar. Also when trying to determine the location of the data for the newly installed calendar , it shows the following:
moz-storage-calendar://
which i do not understand .. Is this a server or online location ?? All the instructions I found so far about calendar location changes state " don't change the location unless 'you know what your doing'.. Well really ? That's an interesting comment.. Why woudl I be looking for help with that item if I already 'knew what i was doing'..
Not only have I lost a whole year of past appointments ( and the future ones) I don't have any confidence in using the updated calendar... Anyone "know what they're doing" that can help?

While I agree that the issue is likely a wrong version of Lightning being installed, to answer the actual question: your local calendars are stored within a database located in your profile (Profile/calendar-data/local.sqlite).
To prevent you from losing data on updates, Lightning will furthermore create backups of your database before the database is updated, if such an update is required (Profile/calendar-data/backup/local.*.sqlite). Thus, if your old version of Thunderbird was ancient and something went wrong, it might be possible to recover your data from such a backup copy.
Regarding your second question: "moz-storage-calendar:// " is kind of a dummy value stating "this calendar is stored locally in your profile, using Lightning's default way to access it". If you use extensions providing calendars (for example ThunderBirthDay) or calendars hosted on the web, different locations are be used. You only want to change the location your calendar is stored on the web and its location changed.

Every version of Thunderbird has a matching version of Lightning. Make sure you have a matching pair. When you do your events should return.
