Microsoft 365 GCC and GCC High AI: what agencies need to know
Which Microsoft AI tools run in government clouds, what differs from commercial, and what to have in place before you turn them on.
Updated
Short answer
Microsoft Copilot, Copilot Studio, Power Automate, and Microsoft Foundry are all available to U.S. government customers. Copilot runs in GCC, GCC High, and DoD, inside each cloud's boundary, with features arriving later than in commercial. Government tenants license Copilot as an add-on to plans such as Microsoft 365 G3 and G5.
What runs in government clouds.
Availability as published by Microsoft, October 2026. Check your own tenant before you plan around a feature.
Microsoft Copilot
Available in GCC, GCC High, and DoD on an add-on license, in Word, Excel, PowerPoint, and Outlook. Copilot in Teams and SharePoint is in GCC and DoD but not yet GCC High. Web grounding is off by default.
Copilot Studio
Available for building agents. Connector catalogs are smaller than commercial, and GCC High limits some agent types.
Power Automate
Available with the core Microsoft 365 connectors. Graph API through HTTP actions covers many gaps.
Microsoft Foundry
Available in Azure Government, which is FedRAMP High authorized, with a model catalog that differs from commercial Azure.
Purview controls
Labels, data loss prevention, audit, and eDiscovery cover Copilot interactions. Some features, such as insider risk management in GCC High, are not available.
Billing
Copilot is an add-on to G3 and G5 plans. Microsoft documents pay-as-you-go for commercial tenants, so government tenants usually plan Copilot Credits in advance.
Before you turn AI on.
These should be in place before Copilot or agents reach staff.
- Correct licensing: Copilot as an add-on to a qualifying government plan, and Copilot Studio capacity for agents.
- Sensitivity labels applied to the content AI can reach.
- SharePoint permissions reviewed, because Copilot answers from whatever each person can open.
- Data loss prevention covering Copilot prompts and responses for your sensitive data types.
- An acceptable-use policy communicated to staff before they are enabled.
- Not sure where you stand? The AI readiness review answers it in two weeks.

Correct licensing, sensitivity labels on the content Copilot can reach, reviewed SharePoint permissions, data loss prevention covering Copilot, and an acceptable-use policy. Training for staff and admins completes the list.
Can Copilot use web results in government clouds?
Web grounding is off by default in GCC, GCC High, and DoD. An admin can turn it on after reviewing what it sends outside the tenant.
