Microsoft is giving Office's user interface a makeover, including tweaks to the ribbon user interface (UI), new colors and updated icons.

Over the next few months, Outlook, Word and other cornerstone Office applications will feature some revamped interface elements intended to help users get the most out of the productivity software suite from Microsoft. They include a simplified ribbon—the once-controversial collection of menu items and tools that reside near the top of Word, Excel and PowerPoint will soon take on a more streamlined appearance meant to help users focus on their work and collaborate with others.

The new ribbon will first appear for some users of the browser-based version of Word on, followed by the Windows version of Outlook for select members of the Office Insider early access program.

Acknowledging that switching up a popular application's interface may not go over well with longtime users, Microsoft is taking a measured approach to releasing the updated ribbon for Word, Excel and PowerPoint, said Jared Spataro, corporate vice president for Office and Windows marketing at Microsoft, in a June 13 announcement.

"Users have a lot of 'muscle memory' built around these versions, so we plan on being especially careful with changes that could disrupt their work," stated Spataro. "We aren't ready to bring the simplified ribbon to these versions yet because we feel like we need more feedback from a broader set of users first. But when we do, users will always be able to revert back to the classic ribbon with one click."

Search will also become more central to the Office experience, Spataro said.

Before users type a query into Outlook's search box, for example, the application will offer recommendations generated by artificial intelligence (AI) technologies and Microsoft Graph, a collection of APIs that deliver contextual information to users based on employee information and content stored across Microsoft's business software and cloud offerings. This so-called "zero query search" functionality will enable users to access contacts, commands and information within Office files with less searching.

Capping off the interface enhancements are new color schemes along with icons that will render better across various screen sizes and resolutions. Taking minimalism to a new level, the icons use a scalable graphics technique to improve accessibility and appear crisp on-screen, Spataro said.

Word for will be the first app to feature the new colors and icons, followed by Word, Excel and PowerPoint for Windows sometime in June for some Office Insiders and Outlook for Windows users in July. Finally, the new colors and icons will hit the Outlook for Mac application in August.
