Set Up Outlook for OAuth 2.0 Authentication

a. Update Microsoft Outlook

Open Outlook.
Go to File > Office Account > Update Options > Update Now.

b. Configure Your Email Account in Outlook

In Outlook, go to File > Add Account.
Enter your Google Workspace email address and click Connect.
Choose IMAP as the account type.
Configure the server settings:
- Incoming Mail Server:
  - Server: imap.gmail.com
  - Port: 993
  - Encryption Method: SSL/TLS
- Outgoing Mail Server:
  - Server: smtp.gmail.com
  - Port: 465 or 587
  - Encryption Method: SSL/TLS (for port 465) or STARTTLS (for port 587)
Click Next.
A Google sign-in window will appear. Enter your Google Workspace email and password, then grant the necessary permissions.
Once authentication is successful, Outlook will finalize the setup. Click Finish to complete.

Important Notes

No Need for Manual Client ID Entry: When setting up Outlook with Google Workspace using OAuth 2.0, you typically don't need to manually input the OAuth Client ID and Client Secret into Outlook. The authentication is handled via the Google sign-in window that appears during setup.
App Passwords: If OAuth 2.0 isn't working due to organizational policies, you might need an App Password. However, Google is phasing out support for less secure app access, so OAuth 2.0 is recommended.
Administrator Policies: Ensure your Google Workspace administrator hasn't restricted OAuth access or third-party mail clients. You'll need to adjust those settings in the Google Admin Console if they have.

Troubleshooting

Authentication Window Doesn't Appear: Ensure that your default browser is up to date and not blocking pop-ups. Also, verify that Outlook is updated to the latest version.
Error Messages During Setup:
- Verify that IMAP access is enabled for your account:
  - Log into Gmail via a web browser.
  - Click the Settings gear icon > See all settings.
  - Go to the Forwarding and POP/IMAP tab.
  - Ensure IMAP Access is enabled.
- Organizational Restrictions: Contact your Google Workspace administrator to ensure that:
  - IMAP Access is enabled for the organization.
  - The necessary OAuth scopes are allowed.
  - External applications like Outlook are permitted.
