User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0 Build ID: 20170808170225 Steps to reproduce: Thunderbird just updated to 56.0b1 and Lightning to 5.8b1. I used to have a Google Calendar and an Office 365 calendar, respectively accessed with Provider for Google Calendar and https://github.com/ExchangeCalendar/exchangecalendar, configured this way https://github.com/Ericsson/exchangecalendar/wiki/How-to-Add-Your-Calendar-to-Thunderbird Actual results: Today I can't access any of the calendars, and I get an error message any time I open TB. I can't say whether it's fault of the providers (not being compatible with new TB) or the new version of Thunderbird. I tried to remove the Office365 calendar and recreate it, but when submitting step 3 of linked configuration page I get this error Error code: 0x80570015 Description: [Exception... "Component returned failure code: 0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE) [nsIJSCID.createInstance]" nsresult: "0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)" location: "JS frame :: resource://calendar/modules/calUtils.jsm -> file:///C:/Users/m.caniparoli/AppData/Roaming/Thunderbird/Profiles/nex6qk7i/extensions/%7Be2fda1a4-762b-4020-b5ad-a41df1933103%7D/calendar-js/calCalendarManager.js :: createCalendar :: line 446" data: no] Looks like it's the same error shown for the Google Calendar on startup Expected results: Errors shouldn't show up and Calendars should be linked
Problem with Google Calendar might be the same as in Bug 1388060 caused by broken OAuth2 authentication in Thunderbird 56.0b1. A fix was already created that will be shipped with the next Beta build. Are you able to connect to your Office365 calendar using the Exchange Provider in a fresh test profile that don't have Google Provider?
Hi, I just tried with a brand new profile and the same error shows up.
Try upgrading to the latest Beta releases (Thunderbird 56.0b3, Lightning 5.8b3, Provider for Google Calendar 3.7b3) to check if connection to Google Calendar works. For problems with Exchange Provider I'd suggest that you search the extension homepage for support.
I downloaded the latest Italian Lightning and the latest Provider from http://archive.mozilla.org/pub/calendar/lightning/candidates/5.8b3-candidates/build1/win32/ and everything looks fine. The external extension still doesn't work and I'll notify them. Thanks!
Hi, Exchange Provider addon has been fixed and will be released with next TB. Everything works for me now.
