Delete attachment api call is giving 500 Internal Server Error

Question

For the following API:

DELETE https://graph.microsoft.com/v1.0/me/events/{eventId}/attachments/{attachmentId{}}

I am getting the following response:

{
    "error": {
        "code": "ErrorInternalServerError",
        "message": "An internal server error occurred. The operation failed."
    }
}

but if I just use this endpoint:

DELETE https://graph.microsoft.com/v1.0/me/events/{eventId}/attachments

the response is successful, can you please help here I am following the following Microsoft learn resource
https://learn.microsoft.com/en-us/graph/api/attachment-delete?view=graph-rest-1.0&tabs=http

Note:

scope of my access token is Calendars.ReadWrite, so access token is valid for my request and also the attachment exist in the event I have cross-checked it multiple times.

Hi @Shubham Yadav,

Thanks for reaching Microsoft.

I tried this API, but I was not able to replicate this issue. I was able to delete the event attachments successfully with the below API and received "HTTP/1.1 204 No Content" response.

DELETE /me/events/{eventId}/attachments/{attachmentId}

As this seems to be a tenant specific issue, I would recommend you to raise a support case with Microsoft Graph, a Support Engineer will be able to assist you better. You can raise support ticket from New support request - Microsoft Entra admin center or https://admin.microsoft.com/#/support/requests.

Hope this helps.
