How do I retrieve the event for an eventMessage

Question

The Graph API v1.0 documentation states that the eventMessage resource type has a relationship called event, which should return

Answer 1

Currently you can only access the event property via the $expand parameter in the URL. So you could do something like:

https://graph.microsoft.com/v1.0/me/messages/<message id>/?expand=
Microsoft.Graph.EventMessage/Event

Or if you're using the Outlook API endpoint, something like:

https://outlook.office.com/api/v2.0/me/messages/<message id>/?expand=
Microsoft.OutlookServices.EventMessage/Event

It is on our roadmap to simplify this, but this is the way it works for now.
