Whether you're searching for people, files, org charts, sites, or answers to common questions, you can use Microsoft Search throughout your workday to get answers. Microsoft Search helps users find the right answers, people, and content to complete their tasks in the app they’re already working in. Users get results that are relevant in the context of the app they search from. For example, when they search in Microsoft Outlook, they find emails, and not SharePoint sites. When they search in SharePoint, they find sites, pages, and files. Whichever app users are working in; Microsoft Search is personal. Microsoft Search uses insights from the Microsoft Graph to show results that are relevant to each user. -
