Create Event in Outlook Calendar based on an expiration date in a SharePoint list - How can I prevent duplicate events?

[TKLR_83]

I am attempting to create an event in my Outlook Calendar based on an expiration date in a SharePoint list. So far, I was able to create a flow that adds the event correctly, but continues to create duplicate events. How can I prevent it from creating duplicates?

Hi @TKLR_83 

Before you adding the event you could check the record already exists by using Get events actions step.

Above to get the total count use the below expression

length(body('Get_events_(V3)')?['Value'])

Then check the length is zero then add the event or ignore it. You may need to extend the Filter Query by using the dates as well (Start and End).

Is there a way to prevent duplicates for a similar flow to group events? (As there is not an option to get events from the group calendar)

Hi @TKLR_83 

You need to use the Graph API to get the group events.
