How to Fix AOL Not Accepting Delivery Error in Office 365 on Windows 11

If you are using Office 365 on Windows 11 and encounter an error where AOL is not accepting your email delivery, it can be frustrating. This problem typically occurs when AOL blocks or rejects emails sent from your Office 365 account.

Understanding why AOL rejects these emails helps in fixing the issue effectively. The cause may be related to security settings, spam filters, or incorrect configurations in Office 365.

This guide will walk you through simple to advanced steps to resolve the delivery error and ensure your emails reach AOL recipients without problems.

Following these instructions carefully will save you time and prevent future email delivery failures.

Quick Note

  • Make sure you have a stable internet connection during troubleshooting.
  • Verify that your Office 365 subscription and email service are active.
  • Check if the email address you are sending to is correct and active.
  • Have your Office 365 admin credentials handy if you need to access advanced settings.

Step 1: Confirm the Email Address and Message Content

Before diving into settings, double-check the email address you are sending to on AOL. Sometimes, simple typos cause delivery failure. Also, ensure that your email does not contain suspicious content or attachments that AOL might flag as spam.

Why this is important: AOL employs strict spam filters. Emails with unusual attachments or links might get automatically rejected.

Step 2: Check Your Office 365 Email Settings

Login to your Office 365 Outlook web portal and verify the following:

  • From Address: Ensure the “From” email address matches your verified Office 365 account.
  • SMTP Settings: Confirm SMTP server details are correct for sending mail.
  • SPF Records: Make sure your domain’s SPF record includes Office 365 servers to authorize sending.

Correct SMTP and SPF settings help AOL recognize your emails as legitimate and not spam.

Step 3: Review Your Domain’s DNS Records

Proper DNS settings are critical for email delivery. Log into your domain registrar’s control panel and check the following records:

  • SPF Record: This should include Office 365 servers to prevent spoofing.
  • DKIM (DomainKeys Identified Mail): Enables email signing to verify sender identity.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance): Helps in preventing fraudulent emails.

If these records are missing or incorrect, AOL may reject your emails to protect users from spam.

Step 4: Check Your Email Blacklist Status

Sometimes, your sending IP or domain might be blacklisted, causing AOL to block your emails.

  • Use tools like MXToolbox Blacklist Check to verify your IP or domain status.
  • If blacklisted, follow the removal process provided by the blacklist authority.

Being blacklisted severely affects email deliverability; resolving this is essential.

Step 5: Adjust Your Office 365 Spam Filter Policies

Within Office 365 Security & Compliance Center, review your spam filter settings:

  • Navigate to Threat Management > Policy > Anti-spam policies.
  • Check if any policies might be causing your emails to be flagged or rejected.
  • Modify the policies to reduce false positives or add AOL domains to safe sender lists.

Proper spam filter configuration helps ensure your emails are delivered without being blocked.

Step 6: Contact AOL Postmaster

If after all these steps emails are still rejected, reach out to AOL’s Postmaster service:

  • Visit AOL Postmaster.
  • Submit a support ticket describing the issue and include bounce-back error messages.

AOL Postmaster can provide details on why your emails are blocked and guide you through unblocking.

Alternative Method: Use a Different Sending Email Address

If the problem persists, try sending emails from a different verified Office 365 email account or a different domain. This can help identify if the issue is specific to one account or domain.
