Microsoft Copilot in Outlook review

For companies that already run on Microsoft 365, Copilot in Outlook is the path of least resistance. Microsoft describes it as a way to catch up on email, draft responses and manage your calendar, and the same Copilot Business license also works in Word, Excel, PowerPoint and Teams, with AI chat grounded in your work data and pre-built research and analysis agents. The add-on was listed at $18 per user per month paid yearly when we checked, down from $21, and $25.20 on monthly billing. Microsoft also sells bundles: Business Standard with Copilot at $23.50 and Business Premium with Copilot at $32 per user per month paid yearly. The tradeoff is that Copilot is a general work assistant, not an email specialist: Microsoft does not document prompt-based inbox filters or replies drafted automatically in the background the way Shortwave or Fyxer AI do. Business plans also top out at 300 users.
