MC1422074: Microsoft 365 Copilot Adds Option for OpenAI-Operated Models via New Admin Setting

📋 Official Microsoft Message Center Announcement

OpenAI models will soon be available as a subprocessor in Microsoft 365 Copilot
Message ID: MC1422074

[What and why:]

To enable OpenAI-operated models in Microsoft 365 Copilot, Microsoft has onboarded OpenAI as a subprocessor, creating the foundation for more model flexibility and quicker access to new AI model innovations. This includes OpenAI’s new family of models, beginning with GPT-5.6, which is now available in Microsoft 365 Copilot. These models are governed by the Microsoft Product Terms and the Data Protection Addendum (DPA), with the same enterprise-grade security, compliance, and data protection commitments you already rely on, except as otherwise disclosed in Microsoft Learn documentation. This setting does not apply to OpenAI models operated by Microsoft Azure OpenAI.

The setting will initially be disabled by default on July 9, 2026. Admins can review and configure the setting at any time in the Microsoft 365 admin center. For eligible customers, if no action is taken prior to July 24, 2026, the setting will be automatically enabled. Admins who do not wish to enable access to OpenAI-operated models should select “No users” before the setting is enabled. 

OpenAI-operated models in the Microsoft 365 admin center are designed to provide administrators with the option to access new AI model capabilities as they become available.
