Local calendar works good. Please help. I'm the one im my company who use Thunderbird with Lightning against Exchange ;)
You need to update your version of the Exchange EWS provider extension. The version you are using is not compatible with Thunderbird 38.
Thanks for rapid answer but how can I do it? Today morning everything was OK on ver. 37.x
Created attachment 8650623 [details] Lightning-error2.png Similar error appears when I try to create new remote calendar - before I enter EWS data.
Based on comments in the other bugs you need at least version 3.4 from https://github.com/Ericsson/exchangecalendar/wiki/Exchange-EWS-Provider
OK. It works. Thank you very much!!
