Office 365 is not available for Linux. Linux users, therefore, have to rely on online versions of the Office 365 software for the most part. These online versions are quite powerful, so that users probably do not notice much difference to the desktop versions.

Users thus may use Evolution if they wish to have the software installed on their devices. For instructions see: Evolution for Linux
