P Cause

There are a few different O365 type login methods. Have you tried them all?

Figured it out. Somehow the jre was headless and not desktop.

Just upgraded to Ubuntu 20.10 beta. When I try to start davmail 5,5,1 froim kubuntu I get xception in thread "main" java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper at java.awt.Toolkit.loadAssistiveTechnologies(Toolkit.java:807) at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:886) at java.awt.SystemTray.isSupported(SystemTray.java:219) at davmail.ui.tray.DavGatewayTray.init(DavGatewayTray.java:236) at davmail.DavGateway.main(DavGateway.java:89) I don't have...

I had the same problem with evolution but then switched to o365manual and it works. A few more steps, but works

I had been running Davmail then used EWS, but admin made me switch bask to Davmail since EWS can't be used. I am getting an error about not finding com.sun.webkit.WebPage. I have openjdk8 and associated libraries. I am using the davmail from the repository and it installed without issue. I had previously been using this same package and am using the same davmail.properties. I have this all running on Fedora xfce spin. Any idea what I need to install?

I keep seeing popups about crlf missing at end of chunk. Using 5.3.1 and Evolution on Ubuntu
