Hi @Lily B ,
According to my research, the function is not officially supported yet.
As a workaround, you can use Outlook's built-in feature to make an event duplicate: double-click on the event to open a new window, then select Recurrence on the ribbon. This way, it becomes recurring event.
Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future, and you can make a suggestion via this link
