Worked on enhancing the OfficeDev/office-js-docs-pr repository by delivering a comprehensive update to the Office Add-ins Known Issues Documentation. Focused on consolidating both active and resolved issues, the update introduced detailed descriptions, status updates, and actionable workarounds for Outlook and Excel add-ins. Leveraged Markdown for clear, structured documentation and applied technical writing skills to ensure accuracy and traceability, aligning the documentation with the issue tracker and reflecting the most recent update date. This work improved developer guidance, reduced support triage time, and streamlined onboarding by providing up-to-date, actionable knowledge for users working with Office Add-ins and related technologies.
