Receiving a “Recipient-Address-Rejected Access Denied” error can be frustrating when trying to send emails on Windows 11. This error typically occurs due to issues with the email server or incorrect email settings. Understanding the root cause helps to fix it effectively.
Fortunately, most solutions are straightforward and require only a few adjustments. Whether you are using a built-in Mail app or a third-party email client, these steps will guide you through resolving this issue.
In this guide, you will find simple and clear instructions that anyone can follow, regardless of technical experience. Let’s start by quickly checking some important points before diving into detailed fixes.
By the end, you should be able to send emails without seeing the recipient-address-rejected error again.
Quick Note: Prerequisites and Initial Checks
Before performing any troubleshooting, make sure of the following:
- Check your internet connection: A stable connection is necessary for sending emails.
- Verify recipient email address: Ensure the email address you are sending to is correctly typed without extra spaces.
- Confirm your email account settings: Double-check your SMTP server address, port number, and authentication details.
- Review your email quota: Some servers reject emails if you exceed sending limits.
Step 1: Confirm Correct Email Address Formatting
The “Recipient-Address-Rejected” error often happens because the recipient’s email address is invalid or mistyped. Start by carefully reviewing the address you’re sending to.
- Open your email client on Windows 11.
- Locate the recipient field and check for any typing errors, such as missing “@” or incorrect domain names.
- Remove any extra spaces or special characters that do not belong.
Why this matters: Email servers reject addresses that don’t follow standard formatting rules, preventing your email from being delivered.
Step 2: Check SMTP Server Settings
SMTP (Simple Mail Transfer Protocol) settings control how your email client sends messages. Incorrect SMTP settings can cause your emails to be rejected.
To verify and adjust SMTP settings:
- Open your email client’s settings or account settings.
- Navigate to the outgoing mail server (SMTP) section.
- Confirm the server address matches your email provider’s recommended SMTP server (e.g., smtp.gmail.com for Gmail).
- Check the port number (commonly 587 or 465) and ensure it matches the provider’s instructions.
- Make sure authentication is enabled and you are using the correct username and password.
Why this matters: Servers use SMTP settings to verify your identity and route emails correctly. Wrong settings block your emails from being sent.
Step 3: Disable Email Filtering or Firewall Temporarily
Sometimes, security software like firewalls or antivirus programs block outgoing emails, causing the recipient address to be rejected.
- Temporarily disable your Windows Defender Firewall or any third-party firewall.
- Turn off email filtering features in your antivirus application.
- Try sending the email again to see if the error persists.
Important: Remember to re-enable your firewall and antivirus after testing to keep your system secure.
Step 4: Clear Email Client Cache and Restart
Cached data in your email client might cause unexpected errors. Clearing the cache and restarting can resolve such issues.
- Close your email client completely.
- Clear the cache or temporary files related to your email client. For example, in the Mail app, you can remove and re-add the account.
- Restart your Windows 11 PC.
- Open the email client and try sending the email again.
This step ensures your client is working with fresh data and connection settings.
Step 5: Contact Your Email Provider or System Administrator
If the error continues, the issue might be on the server side or due to restrictions set by your email provider.
- Reach out to your email provider’s support team for help.
- Ask if your account is blocked or if there are any sending limits exceeded.
- If you are part of an organization, contact your system administrator to check server policies or blacklists.
Providers may reject emails if they detect suspicious activity or if the recipient’s server has specific filtering rules.
Alternative Advanced Options
If you are comfortable with technical settings, you can:
- Enable SMTP Authentication: This ensures that your email client properly identifies you to the server.
- Use SSL/TLS encryption: Secure connections prevent your emails from being blocked by servers.
- Check for IP blacklists: Sometimes your IP might be blacklisted, causing rejections. Use online tools to verify.
