Microsoft widens Legal agent preview to Frontier tenants worldwide
Reviewed by Helen Jones
Microsoft 365 Message Center item MC1388706 says the Legal agent in Microsoft 365 Copilot for Word is expanding to Frontier program tenants worldwide in Public Preview from mid-June 2026. General availability is planned for early July. The agent helps legal users review contracts, identify risks, compare clauses with internal playbooks, and generate edits with Word tracked changes. It is enabled for Frontier tenants and controlled through Frontier enrollment plus Microsoft 365 Copilot licensing, not a separate per-agent toggle.
Before this preview widened, contract libraries, NDAs, and policy documents were already sensitive SharePoint and Teams content, but most small admin teams could still treat legal AI access as a specialist problem. Permission reviews often waited for the next audit. The Legal agent does not change file permissions, but it makes sensitive document access more useful and therefore more visible. If old guest links, broad groups, or missing sensitivity labels exist in legal content, the agent will make those gaps more consequential for Frontier tenants.
Analysis
Run a short permission and sensitivity-label check on contract, NDA, and policy libraries before legal teams start testing the agent. If Frontier is enabled, name the library owner who decides what the agent may be used on.
