Hi @Quang Long

Thanks for reaching out.

For this scenario you can try List event end point try https://learn.microsoft.com/en-us/graph/api/user-list-events?view=graph-rest-1.0&tabs=http, This returns original start date.

But when accessed using Get event https://learn.microsoft.com/en-us/graph/api/event-get?view=graph-rest-1.0&tabs=http. The original start date returned as null.

There was an issue opened a long back, which can be tracked here

https://github.com/microsoftgraph/microsoft-graph-docs-contrib/issues/7267

There is one comment on the above link on Dec 2020, which suggests to use start date instead of originalStart.

You can give it a try to update the start date once for an event and then try to fetch originalStartDate using the select query for that particular event using that particular query.

Refer to the screenshot below.

Hope this helps!
