Jessie Li updated the Microsoft Graph Change Notifications IP addresses documentation in the MicrosoftDocs/microsoft-365-docs repository, focusing on aligning the documentation with a recent migration to a dedicated Vnet using IP Tagging. Working primarily with Markdown and leveraging strong documentation skills, Jessie removed deprecated IP addresses and ensured the documentation accurately reflected current network configurations. The work involved careful version control coordination to maintain consistency across documentation updates. While the scope was limited to a single feature and did not involve bug fixes or code changes, the update addressed an important need for clarity and accuracy in Microsoft Graph Change Notifications documentation.
