Step 3: Adjust Outlook Settings

  • Update Server Settings: Double-check configurations by navigating to File > Account Settings > Account Settings > Email tab. Ensure the server addresses and authentication methods are correct.
  • Repair Account: In Account Settings, select your email account and click Repair. This can help resolve basic configuration issues.
