I understand the gravity of your situation, where your website has been incorrectly flagged as a phishing site by Microsoft Defender, affecting both web access and email deliverability. Here are some steps and considerations to address this issue:
- Review and Rectify Website Security: Ensure your website is secure and adheres to best practices in web security. This includes checking for any vulnerabilities, ensuring SSL certificates are up to date, and your website is compliant with standard security protocols.
- Resubmit Delisting Request: If you've already submitted a delisting request through Microsoft Defender and the issue persists, it's advisable to submit another request. Sometimes, multiple reviews are necessary for resolution.
- Microsoft Support for Phishing Site False Positives:
- Check for Email Best Practices: Ensure that your emails adhere to best practices to avoid being flagged as spam or phishing. This includes proper email authentication (like SPF, DKIM, and DMARC records), maintaining a good sender reputation, and following email content guidelines.
- Contact Microsoft Support: If the issue persists, contact Microsoft Support directly for assistance. They can provide more personalized support and potentially expedite the review process.
- Inform Your Customers: Communicate with your customers about the issue. Provide alternative ways to access your content or services while the issue is being resolved.
- Monitor Your Domain's Reputation: Use tools to monitor your domain's reputation online. Sometimes, other factors (like being listed on DNS-based blacklists) can contribute to such issues.
- Legal Considerations: If this issue is significantly impacting your business, consider consulting with a legal professional to understand if there are any legal remedies available.
Remember, the process of delisting or resolving false positives with Microsoft Defender can take some time. It's crucial to follow up persistently while ensuring all aspects of your website and email practices are compliant and secure.
