Worked on the MicrosoftDocs/office-docs-powershell repository to enhance security policy documentation, focusing on clarifying anti-phishing behavior and domain impersonation handling. Updated the Set-AntiPhishPolicy documentation using Markdown, specifically detailing how BccMessage behavior routes messages to the Junk Email folder for all recipients, including both original and BCC recipients. This documentation improvement aimed to reduce ambiguity for users and maintainers, aligning the user-facing guidance with the actual implemented behavior. The work emphasized clear communication and maintainability, leveraging skills in technical writing and documentation management to help reduce potential support inquiries and ensure accurate understanding of security policy expectations within the repository.
