Graph API: Unable to Retrieve Online Meeting - 404 Error & 3004: Meeting properties are not found

Question

Our application on one of our clients is encountering an issue with the Microsoft Graph API when trying to retrieve details for a specific online meeting using the joinWebUrl.

Below is the API request that results in the error:

GET https://graph.microsoft.com/v1.0/me/onlineMeetings?$filter=joinWebUrl eq 'https://teams.microsoft.com/l/meetup-join/19%3ameeting_***REDACTED***'

The response from this request is a 404 error with the following message:

{
  "client-request-id": "2457e476-efef-4d82-88e0-18007b16f69d",
  "content-type": "application/json",
  "request-id": "c5bb4257-a03f-489e-98ea-823c796a8e1f",
  "message": "3004: Meeting properties are not found"
}

Notes:

• We have verified that the joinWebUrl used in the API request is identical to the one you get on Microsoft Teams' calendar.

Additionally, the client is also unable to save changes in the meeting options from Microsoft Teams, which is resulting in a similar 404 error in the console.

We would appreciate any insights or guidance on resolving this issue.
Thanks.
