Microsoft developers are working on adding Microsoft Search offering to the Windows 10 search boxes of Office 365 enterprise customers. Microsoft says that it should arrive on users’ desktops sometime during this year’s fourth quarter. Microsoft previously tried to forcibly deploy the ‘Microsoft Search in Bing quick access’ Google Chrome extension for some Office 365 ProPlus users. The extension would have forced the browser to use Bing as the default search engine, helping the Office 365 customers to “access relevant workplace information directly from the browser address bar”””
