Outlook GCC High

Connect your AI agents to Outlook GCC High.

This Connector is in Beta

Merge has validated Outlook GCC High against the provider’s documented API and not yet verified it against the live one, so its behavior can differ from the documentation. It carries the same tool surface it will have at general availability. Connectors overview covers the tier and how to turn Beta Connectors off.

Authentication: OAuth or access token. See Magic Link for the runtime auth flow, or Application credentials to bring your own OAuth app.

Sample use cases
