May 6th, 2015 Office 2016 Preview can now be downloaded for free
This desktop edition includes Access (database manager), Excel (spreadsheets), Word (text editor), OneNote (note-taking tool), Outlook (email client), PowerPoint (presentations), and Publisher (page layout and design for publishing). It also includes an online documents manager that can sync with the cloud, as a big focus in this new version is the use of online services through your OneDrive account. In fact, to use many of the tools in the suite, you'll need to log in using your Microsoft account.
The interface has been enhanced, and is now smooth and easy to use. Though it's still a preliminary version, the performance and document-opening speed from a cold start are better than in previous versions, which deserves a round of applause considering that many features require Internet connectivity. (Many of the available templates, for instance, first have to be downloaded from Microsoft servers.)
User interaction is very present, so you can work on a document together with a group of users, even if they don't have the Office package installed, since they can access it through the OneDrive browser. You can also automatically publish content on your blog or share it to your social networks after you generate it on Office, just to mention some of the many new features.
