Solutions to Troubleshoot and Fix the “Your Email Server Rejected your Login” Error in Outlook

Follow the below solutions in the given order to effectively troubleshoot and resolve the “Your email server rejected your login. Verify your username and password for this account in Account Settings” error message in Outlook.

Solution 1: Check Network/VPN and Firewall Settings

Issues with the internet or network connection may prevent access to the email server leading to login failure. In addition, Firewall may also block access to the server. In such cases,

• You can try to restart your router. This will reset and refresh the network connection.
• Check your Firewall settings and ensure that it is allowing the Outlook email client to connect to the internet and not blocking any services.
• If you are using a VPN or proxy server, temporarily disable it.
• Ensure you are using public DNS, such as 8.8.8.8 and 8.8.4.4 and not some AdGuard or other third-party filtering DNS that may block Outlook or your mailbox server.

Solution 2: Verify Username and Password

It’s possible that you are entering the wrong password or using some password-manager to fill the password that may have some space or extra character leading to failure in signing in. Thus, it’s important to double check the username and password for any typos. You can type the username and password on Notepad and then copy/paste them for login to avoid any issue with caps lock or extra space or character.

Solution 3: Reset Password

The password you’re using for login may have expired due to the policies set by your IT team or administrator. Thus, it’s recommended to reset the password. For this,

• Login to the web mail app and choose Forgot password or Reset password option.
• Use your phone number for verification and change the password.

Solution 4: Check Service Health Status

Sometimes, the issue occurs when your mailbox server is down or experiencing some outage or is under maintenance. To check this,

• You can visit the service health status page of your email provider and check if there are any reported issues.
• If there is an ongoing issue, wait until it is resolved and then try to login.
• You may also visit the Outlook web app to check if the server is online and available. Then, login using your email credentials.

Solution 5: Update Server Settings

Incorrect server settings can prevent successful login. Make sure the incoming and outgoing mail server details are configured correctly. For this,

• Open Outlook, go to File > Info > Account Settings, and then select Account Settings from the dropdown.
• Under the Email tab, select your email account and then click Change.
• Then, look under the Outgoing mail server (SMTP) and make sure the server address and port settings are correct. You can confirm these with your ISP or email administrator. You can also refer to the email provider’s documentation for correct settings.
• Also, ensure that under the More Settings > Outgoing Server tab, My outgoing server (SMTP) requires authentication or Require login using Secure Password Authentication (SPA) is checked. This varies based on the Outlook version installed on your system.

• Save the changes and then check if the error persists.

Solution 6: Update Email Client

Outdated Outlook email client may have bugs or lack features that are required by your server to establish a secure connection between the client and the mailbox server. To fix this, you can check and update your Outlook by following these steps:

• You can check and update Outlook by navigating to File > Office Account > Update Options.
• From the available options, choose Update Now.

• If a new update is available, Outlook will start a wizard and download the latest updates.
• Apply the updates and restart the system.

In case this option is unavailable,

• Visit the email client’s official website and download the latest Outlook version on your system.
• Uninstall the older version and then install the new one.
• Configure your email profile and start Outlook.

Alternatively, you can also check Windows Updates. These updates also bring patches for MS Office apps.

Solution 7: Check if Account is Locked

Some email providers temporarily lock the account for security reasons, if the user failed to login into the account after multiple attempts. In such a case, you can stop and wait for some time (like 15-20 minutes) and then try again. If this doesn’t work out or the account remains locked, you can reach out to your email provider for assistance.

Solution 8: Configure App-Specific Password

If you have two-factor authentication enabled, you may fail to login to Microsoft application. Sometimes, this setting is enabled by your administrator. They often link your phone number for the OTP that you need to enter to login. However, the two-factor authentication may not work in some Outlook email clients and you may need to generate app-specific password for login. Therefore, generate the app-specific password and then use that password to login to your email account. For this, you need to,

• Log into your email provider’s account settings and then find the security or 2FA section.
• There, you need to explore and generate an app-specific password that you can use in your Outlook email client.

Solution 9: Create a New Profile and Reconfigure Email Account

If the problem persists, try creating a new Outlook profile and re-adding the email account in your email client under this new email profile. The steps are as follows:

• Open the Control Panel, go to User Accounts, and click Mail.

• In the Mail Setup dialog box, click the Show Profiles button.

• Click Add, type any name for this profile, and click OK to create a new profile.
• Then, follow the sign-in wizard and prompts to configure your email account in the new profile.

• Finally, set the new profile as the default one if there are more profiles. Just select “Always use this profile” and click Apply > OK.
• Also, from the available profiles, select the problematic profile, and click Remove.

Solution 10: Repair Your Outlook Data File (PST)

If the PST file is inconsistent, corrupt, or damaged, Outlook may fail to fetch or write any information in the PST file, which can lead to connectivity issues with the mailbox server and result in the error. You can repair the PST file to fix the issues. The steps to repair the PST file are as follows:

• Close Outlook.
• Press the Windows + R keys, type %programfiles%/Microsoft Office/ or %programfiles(x86)%/Microsoft Office/ and press the Enter key.

• Open the Officexx folder or root/Officexx folder. This may vary based on the Outlook or Windows version installed on your PC.
• Then, find and launch the SCANPST.EXE program. 

• Click Browse to select the PST file located in %localappdata%/Microsoft/Outlook folder or C:\Users\YourUserName\AppData\Local\Microsoft\Outlook folder.
• Once the PST file is selected, click the Start button.

• The tool scans the PST file thoroughly. If any errors and inconsistencies are found, click the Repair button. The repair process may take a while based on PST file size and corruption level.  
• After the repair, start Outlook.

Now check if the Outlook error is resolved and you can login to your email account in Outlook.
