Amit Tendulkar - 2016-08-16

I was able to connect to office365 server till 3 days back. Today I have started getting the following error thrown in the davmail log file. Has something changed on the Office365 side? Probably a change is needed in davmail to fix this issue?

I have installed davmail on Ubuntu 16.04 (64-bit). I am behind a proxy and have configured it through davmail.
