Outlook rich notifications in Microsoft Graph now generally available

Rich notifications are a feature that lets you receive notifications that include resource change data. This allows applications to avoid needing to make a subsequent API call to obtain the changed resource data, improving performance.

Rich notifications for Outlook resources are now generally available on the v1.0 endpoint for all Microsoft Graph customers. We are excited to share this feature with you and help you create more efficient and responsive applications.

Why use rich notifications?

Rich Notifications are designed to replace the Outlook REST notifications, which are currently used by many customers but have some limitations, such as:

Not supporting delta queries, which increases the risk of missing changes.
Not being consistent with the Microsoft Graph API design and documentation.

We recently announced the decommissioning of Outlook REST, and we encourage Outlook REST users to migrate to Microsoft Graph as soon as possible. Rich notifications are more reliable, secure, and consistent with the Microsoft Graph API. You can leverage the Microsoft Graph SDKs and tools to simplify your development and integration.
