Editing Recurring Events
A recurring event is designated by a pair of circling arrows on your calendar

You can Edit or Delete a single recurring event, or all instances of an event.
To edit or delete a recurring event, click on the event to activate the options to modify that event.

If you click on either edit or delete, you will have the option to edit or delete All instances or This instance

When you choose to edit This instance, only the individual event will be affected. For example, if a meeting time or location changes, you can changes the specifics of that event without affecting the other meetings.
Once an individual event has been modified, it is no longer considered a recurring event. Therefore, future changes to All Instances will not affect that event.

The edited event will no longer have the circling arrows which signify a recurring event
