About this tag
Microsoft Graph is the unified API gateway for Microsoft 365, Entra ID, Exchange Online, Teams, SharePoint, Intune, and other cloud services. Discussions on WindowsForum.com cover security vulnerabilities like CVE-2026-49159, which exposes information disclosure risks in the Graph API layer. Administrators are migrating from Exchange Web Services (EWS) to Graph before EWS retirement in October 2026, using tools like EWSAllowedAppIDs and DavMail 6.8. Graph now supports archive mailboxes for Purview and browser push notifications for admin dashboards. Threat hunting involves correlating Graph, Exchange, and Entra logs to detect assistive agent abuse. Resource mailbox utilization reporting also relies on Graph queries.
