davmail

DavMail is an open-source gateway that bridges Microsoft Exchange and Microsoft 365 with standard email, calendar, and address book protocols. The tag covers the release of DavMail 6.8, which adds active Microsoft Graph support in its graphical interface, improving calendar behavior and authentication handling. This update is significant as Microsoft phases out Exchange Web Services (EWS), making DavMail a key tool for users of Thunderbird, CalDAV, CardDAV, or Unix mail stacks who need continued access to Exchange and Microsoft 365 services. The tag includes discussions of the software's configuration model, Linux packaging, and macOS compatibility.
