This guide walks you through connecting your Google Workspace mailbox to Microsoft Outlook on Windows using modern authentication (OAuth) or IMAP/SMTP. Follow the steps carefully and use the troubleshooting section if something doesn’t work as expected.
Important: If your organization enforces 2‑Step Verification, you’ll sign in with Google’s secure window (OAuth). If basic passwords are used, you must enable IMAP in Gmail settings and use the correct IMAP/SMTP servers and ports.
