Reasons for the “Your Email Server Rejected Your Login” Error in Outlook

- Bugs or glitches in the Outlook client itself can interfere with login processes.

- Temporary internet or DNS issues can block Outlook from connecting to your email server.

Solutions to Fix the “Your Email Server Rejected Your Login” Error in Outlook
To resolve the error “Your email server rejected login. Verify your username and password for this account in Account Settings”, follow the solutions below in order. These steps will help you identify the root cause and restore access to your Outlook email account.
Solution 1: Check Network, VPN, and Firewall Settings
A weak internet connection or overly restrictive network/firewall settings can block Outlook from connecting to your mail server.
What to do:
- To restore your internet connection, restart your modem or router.
- Check your firewall settings and ensure Outlook is allowed to access the internet.
- If you’re using a VPN or proxy, temporarily disable it and try logging in again.
- Use public DNS servers like 8.8.8.8 and 8.8.4.4 instead of third-party DNS filters (e.g., AdGuard), which may block Outlook or your mail server.
Solution 2: Verify Username and Password
Even a small typo or extra space can prevent a successful login, especially if using a password manager.
Tips:
- Manually type your username and password into Notepad first.
- Then copy and paste them into Outlook’s login fields to avoid issues with auto-fill, caps lock, or hidden characters.
- Ensure you’re entering the correct email address format (e.g., user@domain.com).
Solution 3: Reset Your Password
Your email password may have expired, especially if you’re under a company policy that enforces regular password changes.
Steps:
- Go to your webmail login page.
- Click “Forgot password” or “Reset password.”
- Follow the prompts using your registered mobile number or recovery email.
- Set a new, strong password and use it to log in to Outlook.
Solution 4: Check Mail Server or Service Health Status
Outlook may fail to connect if your email provider’s servers are down or under maintenance.
Steps:
- Visit your email provider’s Service Health Status or System Status page (e.g., Microsoft 365, Gmail, Yahoo).
- Look for any ongoing outages or maintenance notifications.
- If issues are reported, wait until service is restored, then try logging in again.
- Alternatively, try accessing your account via Outlook Web App (OWA) to check if the server is online.
Solution 5: Update Server Settings
Incorrect or outdated server settings are a common cause of login issues in Outlook. Verifying and updating the incoming and outgoing server details can help resolve the “email server rejected your login” error.
Follow these steps:
- Open Outlook and navigate to: File > Info > Account Settings > Account Settings
- Under the Email tab, select your account and click Change.
- In the account settings window, check the following:
- Outgoing Mail Server (SMTP): Make sure the server address and port number are correct.
- Confirm these settings with your email provider, ISP, or IT administrator. You can also refer to your email service’s official documentation.
- Click on More Settings, then go to the Outgoing Server tab:
- Ensure “My outgoing server (SMTP) requires authentication” is checked.
- If required by your provider, enable Secure Password Authentication (SPA).
- Save the changes and restart Outlook to check if the error is resolved.
Keeping your server settings updated ensures a smooth and secure connection between Outlook and your email provider.
Solution 6: Update Your Email Client
An outdated version of Outlook may lack compatibility or security features required by your mail server, leading to login failures.
To update Outlook:
- Open Outlook and go to:
File > Office Account > Update Options > Update Now - Outlook will start downloading and installing any updates that are available.
- Once completed, restart your system.
If the update option is unavailable:
- Visit Microsoft’s official website and download the latest version of Outlook.
- After removing the previous version, install the most recent one.
- Reconfigure your email profile and relaunch Outlook.
Also, check for Windows Updates under Settings > Update & Security. These may include important patches for Office apps, including Outlook.
Solution 7: Check if Your Email Account is Locked
Some email providers implement automatic temporary account locks after multiple failed login attempts as a security measure.
What to do:
- Wait 15–20 minutes and try logging in again.
- If the issue persists, contact your email provider’s support to unlock your account or verify any security restrictions in place.
Solution 8: Configure an App-Specific Password (For Accounts with Two-Factor Authentication)
If two-factor authentication (2FA) is enabled on your email account, standard login credentials may not work in some email clients, including older versions of Outlook. In such cases, you’ll need to use an app-specific password.
Steps to generate and use an app-specific password:
- Log in to your email provider’s web account.
- Navigate to the Security or 2FA settings section.
- Find the option to generate an app-specific password.
- Copy the generated password and use it in place of your regular email password when configuring Outlook.
App-specific passwords allow Outlook to connect securely without compromising your 2FA protection.
