Editing a recurring event (how to choose "This event only," "This and following," "All")

When you edit a recurring event, a screen appears for choosing the scope to apply the change. Choose based on your situation.

• This event only — When you want to change the time or content for just that day (e.g., move only this week's meeting 30 minutes later). It's recorded as an exception event, and the other occurrences stay as they were.
• This and following — When you want to change the ongoing rule from the selected event onward (e.g., change the day of the week starting next month).
• All — When you want to change everything, including the past (be careful, as history is also rewritten).

Deletion can likewise be chosen from the same three modes.
