1. Check Internet & Server Access
  • Make sure you're connected to the internet.

  • Test webmail (e.g., mail.yourdomain.com) to confirm your account is working.

  • If webmail also fails, contact your email provider.

2. Remove & Re-add the Account
  1. Open the Outlook Mail app.

  2. Go to Settings (⚙️) > Accounts.

  3. Select your email account > Delete account.

  4. Add the account again using correct settings (IMAP/SMTP preferred).

3. Use Advanced Setup if Needed

If standard setup fails:


  • Choose Advanced setup when adding the account.

  • Enter the correct server settings:

    • Incoming (IMAP): mail.yourdomain.com, Port 993, SSL: Yes

    • Outgoing (SMTP): mail.yourdomain.com, Port 465 or 587, SSL: Yes

4. Check Two-Factor Authentication

If you use 2FA (e.g., Gmail, Yahoo, iCloud), generate an App Password via your email provider and use it instead of your main password.

5. Temporarily Disable Antivirus/Firewall

Third-party security software may block syncing. Temporarily disable it to test, or allow the Outlook Mail app through your firewall.

6. Check Privacy Permissions

Ensure Outlook has access to email and calendar:


  • Go to Settings > Privacy & Security > Email / Calendar.

  • Enable “Allow apps to access email/calendar.”

7. Fix Common Errors
  • Account settings out of date: Likely a wrong password. Click Fix account and update your password.

  • Certificate error: Enable SSL in sync settings.

  • Error 0x80072726: Often caused by firewall/antivirus—follow step 5 above.

Always ensure Windows and the Outlook app are up to date via Settings > Windows Update.
