Worked on enhancing documentation for SharePoint Online tenant renaming error handling within the MicrosoftDocs/SupportArticles-docs repository. Focused on expanding the coverage of error codes, specifically updating information for error code 771 and adding related codes 1090, 1091, and 1092. Used Markdown to update errors-when-renaming.md, ensuring that troubleshooting guidance became more comprehensive and actionable for end users. The work centered on improving documentation clarity and reducing support escalations by making error information more accessible. Emphasized traceability by associating all changes with a single, versioned commit, demonstrating attention to documentation quality and process within a collaborative technical environment.
