The GNOME project has released version 2.26 of its eponymous open source desktop environment for Linux. It adds support for MAPI to Evolution, the messaging client in GNOME, allowing it to work with all versions of Microsoft's Exchange Server. It also adds the ability to open Outlook mailbox (.pst) files.
While "release early, release often" can make reporting on new versions of open source software an exercise in trivia, this time the changes introduced could increase the level of adoption in companies that haven't previously had many Linux desktops. Before this latest release, Evolution could only talk to Exchange servers using a SOAP interface, which wasn't supported on all versions of Exchange, and didn't provide the same level of functionality as MAPI, Microsoft's native messaging protocol. Now Evolution should be able to connect to any version of Exchange Server.
