Ever wanted to get rid of Outlook ? DavMail is a POP/IMAP/SMTP/Caldav/Carddav/LDAP gateway allowing users to use any mail client with Exchange, even from the internet through Outlook Web Access on any platform, tested on MacOSX, Linux and Windows
Warning to KDE users: It's a great utility and a few weeks ago, I would have given it 5 stars. Unfortunately, it no longer works in any OS running KDE 5, which includes Kubuntu 16.04, the latest LTS distribution. No system tray icon = no way to access DavMail settings. Confirmed bug #1448512 is over a year old now and as soon as everyone else still on KDE 4 goes to KDE 5, it's goodnight DavMail. If you're a Kubuntu user and this affects you, please look up this bug on Launchpad (URLs are apparently verboten here) and register yourself as being affected by this bug.
