• Create and publish company-wide prompt collections in the Copilot Prompt Gallery.
• Access MCP-based agents directly in Word, Excel, PowerPoint, Outlook, and Catalyst.
• Create brand kits by uploading a brand guidelines document.
• Manage Federated Copilot Connectors from the Microsoft 365 admin center Connectors tab.

• Admins can review and approve submitted agents in Microsoft 365 admin center before they appear under Built by your org in the Agent Store.
• Federated Copilot Connectors can be deployed or updated from Microsoft 365 admin center > Copilot > Connectors.
• Confluence and ServiceNow connector access now depends on hierarchical ACL evaluation.
• Microsoft Edge v.149 is mentioned as a separate Web UI update and is not specific to 365 Copilot functionality.
