Davmail hangs on manual O365 authentication

[ermin-sakic]

Following the attempt to manually log-in into Office 365 using provided link, pressing Open / or blue highlighted text results in a frozen window with the attached error.

I can, however, reproduce this only on a single machine. All of my machines are running Ubuntu 20.04 with appropriate packages and OpenJDK 1.8.0_252. This is a multimonitor setup.

This error is related to SWT, please check that you have the same package version as your other machines.

A workaround may be to disable SWT completely, check launch script for details: https://github.com/mguessan/davmail/blob/master/src/bin/davmail
