Microsoft Search, the new enterprise search experience that provides personalized results across Microsoft 365 experiences has started rolling out to all Microsoft 365 and Office 365 commercial subscribers. The Redmond giant announced the general availability at its Build 2019 developer conference this morning, adding that all customers should get the new Microsoft Search experience at the end of May.

For those unfamiliar, Microsoft Search leverages AI and the Microsoft Graph to show relevant organizational content such as contacts, Office 365 documents, and more. It works as a universal Search box that can be found on various Microsoft products including Office, SharePoint, OneDrive, Outlook, Windows, and Bing.

Microsoft Search was first announced back at Microsoft’s Ignite conference in September, and it first launched in preview on, and the SharePoint mobile app. Microsoft is now ready to make the supercharged search experience available on many more apps, including the built-in Search functionality on Windows 10. It’s probably not a coincidence that Microsoft has finally separated Cortana from Windows Search in the Windows 10 May 2019 Update, as Windows Search is about to become much more useful for Microsoft 365 and Office 365 customers.
