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.

    Microsoft Copilot Security: Graph Grounding, Permissions and Governance for Windows IT

    For years, enterprise chatbots had the conversational agility of a parking meter. If you didn’t feed them the exact keyword they were programmed to recognize, they spat out a canned error message or routed you into a helpdesk queue where tickets went to retire. By late 2026, that rigid...

    Microsoft Entra’s Governance Update: What IT Must Do

    Microsoft’s latest Entra changes are less a single product launch than a set of operational signals for identity teams: govern the tenant sprawl that already exists, prepare for permission behavior to tighten, and treat several AI and hybrid-identity additions as previews rather than finished...
