Microsoft Copilot: SpaceXAI subprocessor admin setting

SpaceXAI is added as a Microsoft Copilot subprocessor, enabling Grok models in Word, Excel, and PowerPoint for eligible Frontier customers starting September 18, 2026. The SpaceXAI admin setting is disabled by default and must be enabled by admins. Availability excludes EU, EFTA, UK, and government clouds. What and why: As part of our efforts to expand model choice in Copilot, SpaceXAI has been added to Microsoft’s Online Services Subprocessor List, published in the Service Trust Portal. Being listed as a subprocessor does not, by itself, mean SpaceXAI is enabled for your organization or that SpaceXAI is processing your data. Access to Grok models is governed by a new SpaceXAI admin setting under AI providers operating as Microsoft subprocessors in the Microsoft 365 admin center. The setting is disabled by default. Eligible customers participating in Frontier must explicitly enable the setting before Grok models can be used in their organization. If enabled, Grok models will be available in Word, Excel, and PowerPoint. Users can select Grok from the model selector when using Copilot in those apps. When the SpaceXAI setting is enabled, Microsoft’s Product Terms and Data Protection Addendum (DPA) apply to the use of Grok models, except as otherwise disclosed in Microsoft Learn documentation.

Impact on your organization: Who is affected: Customers participating in Frontier are eligible to access Grok models in Word, Excel, and PowerPoint. Note: The following customers are not eligible and won’t see the SpaceXAI admin setting during initial rollout even if participating in Frontier. Tenants in the EU, EFTA, and the UK. Government cloud customers (GCC, GCC High, DoD). Administrators managing model access controls in the Microsoft 365 admin center. What will happen: The SpaceXAI admin setting will become available to eligible Frontier customers and will be disabled by default. Grok models are not available, and no customer data will be processed by SpaceXAI, unless an admin enables it. If the admin setting is enabled, users will be able […]
