Generally available: Azure Event Grid partner events

Partner events is an Azure Event Grid feature that allows external systems, typically SaaS providers and platforms, to publish events so that your applications can subscribe to them. This way, your solutions can react to events that originate in non-Azure services and implement architectures across network boundaries.

 Following is the list of available external services/platforms (aka “Partners”) from which you can subscribe to events using the Partner Events feature:

1.  Auth0
2. Microsoft Graph API. Microsoft Graph API makes available events that originate in Azure AD, Microsoft Outlook, Microsoft Teams, Microsoft SharePoint, Microsoft Conversations, and Universal Print. Security alert events sourced from different security providers are also available.
