Copilot in Outlook makes inbox management easier with AI-powered assistance to help you write emails quickly, turn long email threads into short summaries, and even create a meeting invitation from within an email thread.
Important: Copilot in Outlook only supports work or school accounts, and Microsoft accounts using outlook.com, hotmail.com, live.com, and msn.com email addresses at this time. Email accounts from third-party email providers such as Gmail, Yahoo, and iCloud can use Outlook, but won't have access to Copilot features.
