Synchronize Outlook Calendar Events from Excel Spreadsheet

This question has been floated in the forums before but I've been unable to implement the solutions. Newbie at flow, pretty good with excel.


End goal is an Outlook calendar whose events are pulled from an excel spreadsheet stored on Onedrive. A scheduled flow would pick up updates from the spreadsheet and apply them to the calendar, updating changes events and adding new ones.


I can build a flow which adds the events to the calendar using list rows present in a table and create event (v4) but every time it re-runs, it duplicates the events.


Ideally, the existing events would be updated and new events added. A backup is that the old events are cleared and new events added. I understand the key here is an event ID, but the excel docs has no idea what those IDs are. 


Thanks in advance!

Hi @BarvoDelancy ,


You could create a column in the Excel table to record the EventId, and update the column whenever the event is created.

Also, check if the corresponding EventId already exists before creating the event, if it is, update the event, if not, create a new event.
