This functionality is only available on Outlook Web Access (aka OWA, aka Outlook on the Web) and new Windows Outlook client.
You can now set a setting to automatically decline conflicting request meetings.
From time to time, you may receive request meetings which are conflicting with events already in your calendar; most of the time you ended to decline the request.
Well, good news as now you can get your mailbox to do it for you automatically by setting the new “Automatically decline invitations that conflict with existing events” on your mailbox.
If you enable this setting, I would recommend to enable the “Save declined events” too just to keep track and allow you to decide which event you want to join
This capability is only available through Outlook Web Access or the new Outlook client
