Deleted entries still showing

It’s frustrating that Outlook does that instead of just deleting them. But you should be able to remove them from the calendar with the hidecancelledevents parameter:

Thank you very much for your quick reply ??

Unfortunately that I’ve added that parameter, purged the cache and the cancelled events are still showing.

I might need to see the specifics of your setup to troubleshoot this further. Can you please use the Pro Support Request Form (it’s fine if you don’t have a Pro license) to send me your exact shortcode and System Report? Thanks.

Thank you, I have now done that

We received very prompt assistance from the plugin developer who advised we exclude cancelled events via a parameter in the short code which resolved the issue.
