How to hide canceled/deleted events in Google Calendar, when syncing events from Exchange? I'm using the latest version of Google Calendar on Android 5 to sync events from an Exchange server. However canceled and deleted events keep showing up in the Calendar, even though I no longer see them on the Exchange server.

Is there a way to hide or delete them from Google Calendar as well?
As of 2017 it's impossible to hide cancelled events from Google Calendar. So unfortunately you would have to delete them manually.
