Re: prevent users from deleting sharepoint calendar list item if the logged user is not the organizer or creator
Hi @jdanielhdezr ,
If I understand correctly:
You want to prevent users from deleting a SharePoint calendar list item, specifically when the logged-in user is not the item's organizer or creator. You want to limit item deletion exclusively to the user who originally created it. And "organizer" being the person who scheduled or created the calendar event. This "organizer" would be a SharePoint column that you created for this list, as there is no built-in organizer column (i.e. Creator and Organizer are different people, so are different SharePoint columns).
Here are two suggestions you can try:
(1) Change the Advanced settings so that only the Creator can edit the calendar items they have created, everyone else can view (i.e. Read):



(2) Grant Edit access to the Calendar item to the organizer when a new item is created

(However, if the organizer is later changed, the flow will need to use a different trigger (when an item is created or modified) and check if the organizer was changed. But this is more complex and a bit more work).
