<AccordionGroup>
  <Accordion title="What is microsoft365.com/setup?">
    It is Microsoft's official page for redeeming a Microsoft 365 product key and linking the subscription to your Microsoft account. Read [what microsoft365.com/setup is](/blog/https-microsoft365-com-setup).
  </Accordion>

  <Accordion title="Is https microsoft365 com setup the same as https www microsoft365 com setup?">
    Yes. Both addresses lead to the same official setup page. Type either one directly into your browser rather than clicking ads.
  </Accordion>

  <Accordion title="Where do I find my product key?">
    On the retail card (often under a scratch-off strip) or in the confirmation email from the store where you bought it.
  </Accordion>

  <Accordion title="Can I use my product key more than once?">
    No. A key is redeemed once and then tied to your Microsoft account. To reinstall later, sign in to your account and select **Install apps**.
  </Accordion>

  <Accordion title="Do I need microsoft365.com/setup for a business plan?">
    Usually not. Business plans are set up by an admin in the Microsoft 365 admin center, and users sign in with a work account. See [microsoft365.com/setup for business](/blog/microsoft365-com-setup-business).
  </Accordion>

  <Accordion title="I redeemed the key with the wrong account. What now?">
    Check which account holds the subscription by signing in to each one. See [linking your Microsoft account](/blog/link-microsoft-account-setup) and contact [Microsoft Support](https://support.microsoft.com) if you need to move it.
  </Accordion>

  <Accordion title="Someone called offering to help me set up Microsoft 365. Is it safe?">
    Be very cautious. Never share your product key, passwords, or remote access with unsolicited callers. Read [how to avoid setup scams](/blog/official-setup-url-safety).
  </Accordion>

  <Accordion title="The setup page or installer is not working.">
    Try a different browser, clear your cache, and confirm you are signed in to the right account. See the [troubleshooting guide](/blog/microsoft365-setup-troubleshooting).
