DavMail

Exchange gateway for standard mail and calendar clients

About DavMail

DavMail is a free, open source gateway that sits in front of Microsoft Exchange and Office 365 and translates it into standard protocols. It provides POP, IMAP and SMTP for mail, CalDAV for calendars, CardDAV for contacts and LDAP for address book lookup, so clients such as Thunderbird or Apple Calendar work with Exchange servers, including through Outlook Web Access from behind a firewall. It runs in Java on Windows, Linux and macOS.
