Follow these steps in order, checking Outlook after each major step.

1. Enable IMAP in Gmail
   1. In a browser, go to Gmail and sign in.
   2. Select the gear icon > Settings.
   3. Go to Forwarding and POP/IMAP.
   4. Under IMAP access, select Enable IMAP.
   5. Select Save Changes.
2. Make sure required folders are visible to IMAP
   1. In Gmail, go to Settings again.
   2. Select the Labels tab.
   3. For Inbox, Sent Mail, Trash, and All Mail, make sure Show in IMAP is selected.
   4. Optionally enable Show in IMAP for any other labels that should appear in Outlook.
3. Check Outlook 2021 account settings (IMAP/SMTP) When adding the Gmail account manually in Outlook 2021, use these server settings:
   • Incoming mail (IMAP) server: imap.gmail.com
     • Requires SSL: Yes
     • Port: 993
   • Outgoing mail (SMTP) server: smtp.gmail.com
     • Requires SSL: Yes
     • Requires TLS: Yes (if available)
     • Requires Authentication: Yes
     • Port for SSL: 465
     • Port for TLS/STARTTLS: 587
   • Account name/username: full Gmail address
   • Password: Gmail password (or app password if using 2‑step verification)
4. Fix the known Outlook–Gmail sign‑in issue (if seeing “Sorry, we could not sign you in to Google – IMAP”)
   1. Open Outlook or any other Office app.
   2. Select File > Office Account.
   3. Under Account Privacy, choose Manage Settings.
   4. Check Enable optional connected experiences.
   5. Restart Outlook and add the Gmail account again.
5. Refresh Outlook after changes After changing Gmail IMAP and folder settings, allow up to 15 minutes for sync to refresh, then restart Outlook and test sending/receiving.

If the error persists after all of the above, verify that Outlook 2021 is fully updated, then remove and re‑add the Gmail account using the settings above.
