Evolution review

Evolution is the pick for Linux users stuck with a work calendar on Microsoft Exchange or Microsoft 365. The GNOME project describes it as a personal information manager with integrated mail, calendaring and address book, and it can connect to Exchange through the optional Exchange Web Services extension, which also appears in the Flathub release notes. Its data server also handles CalDAV accounts, iCloud servers and OAuth2 sign-ins, and the same server powers GNOME Calendar, so the two apps can share accounts. The project stresses standards compliance and supports a wide range of data formats and protocols, and an EteSync add-on is available for people who use that service. Evolution is free, open source and shipped by most distributions, with the latest stable release also on Flathub. It is not as quick to learn as GNOME Calendar, since mail, contacts and calendar share one dense window, and it does not run on Windows. For Exchange on Linux, though, it is the most direct free route.
