It is technically feasible – even though Onpipeline was not designed with this logic – to sync multiple users to the same external calendar. All events would be cloned and distributed as a single event.
This is not a conventional use, but in some situations, it could be functional.
Important: Obviously, this method can create confusion and loss of control, such as an event being mistakenly deleted by a user on all calendars due to the command passing through the sync of the external calendar. E.g. User A > Google Calendar > User B.
We invite you to carefully consider and test such a configuration before applying it, especially because the entire personal calendar on Onpipeline would be cloned and synchronized.
