Microsoft is removing the Sidebar feature from Microsoft Edge, starting with users of Microsoft accounts (MSA), though no specific timeline has been provided. The Sidebar, which allowed users to integrate web apps like Outlook and Bing, will no longer support adding new apps, and its quick access list will be gradually removed. The Copilot feature within the Sidebar will remain unaffected. CEO Satya Nadella stated that Microsoft is committed to enhancing user engagement across its platforms, including Edge, which has gained market share for 20 consecutive quarters.
