I followed the instructions at "event-list-attachments" to view the list of attachments for the event, but only file attachments were viewed and OneDrive attachments were not viewed.
How do I get reference attachments?

I got the same issue when try to list attachment from a message. Only file attachments fetched
I already read that document!
First, I need to know the reference attachment's ID!
Refer : https://learn.microsoft.com/en-us/graph/api/event-list-attachments?view=graph-rest-1.0&tabs=http
What I did : https://graph.microsoft.com/v1.0/users/userPrincipalName/events/event-id/attachments
But, There is no refence attachment in the result. only file attachment

Hi Ram
Thank you for reaching out to Microsoft!
For getting reference attachment, please refer this documentation below:
https://learn.microsoft.com/en-us/graph/api/resources/referenceattachment?view=graph-rest-1.0
Additionally, please try this API
GET /users/{id | userPrincipalName}/events/{id}/attachments/{id}
Hope this helps.

Any updates on this?
I’m experiencing the same behavior. When a OneDrive file is attached in Outlook online, it appears to be rendered as an inline hyperlink inside the HTML body of the event instead of being returned as a referenceAttachment via the attachments API.
Is this the expected behavior for Outlook online?
Note: I haven’t tested whether Outlook desktop client can create a referenceAttachmentor not.
