Microsoft has updated the release model for Microsoft 365 Copilot, allowing administrators to assign Entra ID groups to specific update channels for streamlined deployment control.
Microsoft introduced a new admin setting in the Microsoft 365 admin center to control AI models in preview, including Anthropic’s Mythos-class models with data retention.
The Frontier Admin Control now supports Entra ID groups again for managing Frontier enrollment, alongside individual user assignments. Microsoft had removed this option in November 2025.
Microsoft is adding support for prepaid Copilot Credits in Microsoft 365 billing policies, so organizations can use agents in Copilot Chat without connecting to an Azure subscription. This enhancement applies to users without a Microsoft 365 Copilot license.
A new Voice and Face enrollment report in the Teams admin center gives admins visibility into enrollment status and metrics across the tenant for the last 180 days.
Microsoft is expanding the Teams Reader role with broader read-only access to the Teams Admin Center, PowerShell, and Microsoft Graph APIs.
A new control in the Microsoft 365 Admin Center lets administrators assign third-party model provider access to specific users or Entra ID groups, rather than enabling it for the entire tenant. The setting is also enforced across Power Platform environments and Copilot Studio agents.
The Frontier Admin Control is being updated with a single control point for managing access to experimental Frontier features across Microsoft 365 apps, platforms, and Copilot agents.
Microsoft is rolling out a new three-tier release model for Microsoft 365, starting with Copilot in May. The new Frontier, Standard, Deferred tiers should give organizations greater control over when users receive new features.
A new External Domain Anomalies report in the Teams admin center should provide an overview of how users in the tenant interact with people outside the organisation and flag sudden spikes or unusual engagement that fall outside normal patterns.
