I've recently upgraded Thunderbird to version 52.0 from 45.8 and Lightening from 4.7 to 5.4. My Outlook calender is NOT visible after that. When tried to do "Check Server and MailBox" from AWS properties option in Lightening, it gave an error as follows
Error during checking of server and mailbox: HTTP Client error 401: Unauthorized
URL:https://xxx-owa.xxxxx.xxxxxx.xx/xxxx/Exchange.asmx
(Code: -19)
EWS plugin version: 3.3.2. Tried upgrading to version 3.9. But, that didn't help.
PS: Downgrading Thunderbird (to 45.8) and Lightening (to 4.7) again started working without any change in settings. But the new versions are not.
