Summary:
Microsoft 365 Copilot Tuning public preview (mid-February to late March 2026) introduces customizable agent templates in Agent Builder for organizations with 5,000+ Copilot licenses. It uses tenant-isolated SharePoint snapshots for tuning, with admin controls for access, data privacy safeguards, and regional processing considerations.
Details:
[Introduction]
Microsoft 365 Copilot Tuning is introducing new templates in Agent Builder designed for tasks such as drafting complex documents, validating documents against organizational guidelines, and editing to match a distinct writing style. Users with Copilot Tuning enabled can further customize the template-based agents by tuning the context, tools, and underlying models with their organization's proprietary data, processes, and standards. This empowers your teams with customized agents aligned to how your organization works.
[When this will happen]
Public preview (Worldwide): We will begin rolling out in mid‑February 2026 and expect to complete by late March 2026.
