Right now, if I have a flow that creates SharePoint Calendar events, I have to manually edit each event's recurrence and All Day Event status within SharePoint. I have been able to create a flow that creates an item, which in turn triggers a workflow in SharePoint Designer to make that event an All Day Event. However, setting the Recurrence in Designer is limited to entering Yes/No, which gives an error once the workflow is triggered. Also, I haven't found any manageable solution to alter the RecurrenceData without having to resort to using C#, VB, or REST API. I think workflows would be a lot easier and more efficient for everyone if All Day Event and Recurrence could be edited within Microsoft Flow.
