We found that the iCalUId of some customers is empty, which caused us to encounter some problems when obtaining the calendar of this customer
Most of the users in our response have iCalUId, but some users do not have iCalUId, so under what circumstances will an empty iCalUId be responded? Not just iCalUId, meeting_number and join_url are also empty.

David Perez 0 Reputation points2024-03-18T09:21:44.72+00:00 Any update on this issue please? We are having exactly the same problem. Most events contain the iCALUId but we do find that some have an event Id but the iCalUId is null:
It's unclear to me if this issue has been accepted and is being actively investigated. Please advise.
