If you want to manually block out a day on the calendar to make a resource like a party room unavailable, you can exclude that one day without having to create a rule.
- On the main calendar window click Manage Schedule.
- Click on the Resources tab.
- Right click on the resource for the day you wish to delete and select Exclude This Instance.
- The resource will now be unavailable for that day. You won’t be able to book any events that require that resource for that day.
- Click Close to finish.
