My lightning calendar disappeared from my Thunderbird starting from 01-12-16. Can not find or reinstall it. Have TB 45.5.1 - Lightning is not supposed to be integrated?

I tried to download and open this file: lightning - 4.7.4 - sm + tb - windows.xpi with Thunderbird several times this afternoon without effect. Just tried again, and it works well - is no longer a problem. Thanks anyway. Maybe this will help someone else. Just keep trying to re - install file.

Sorry, no it is not "integrated". He is always implemented as an add-on, the only difference being that it is automatically included in a new download of Installer and there is now a checkbox allowing you to decide if it use or not.

Thus, all the usual tools for adding, removal, activation and deactivation of the modules are still topical.

Open tools | Add - ons, locate lightning, remove it, restart Thunderbird, go to tools | Modules and reinstall Lightning as if it's an add-on on a regular basis.
