How to return Outlook calendar Event ID to SharePoint list
I have a Flow which is triggered on creation of a new record in a SharePoint list and which creates a corresponding Outlook calendar event. I have this working well, but I wanted to store the ID of the created event back in the SharePoint record so as to be able to update the same event later if the SharePoint record is altered.
I added a Single Text column to the SharePoint list and added a new Update item step after the event creation to write back to the SharePoint record. I added the dynamic content value of Id (the event's unique identifier) to the new SharePoint field:
New Flow action
I save the Flow and it then runs successfully but no value is stored in the new SharePoint field. When I return to the Flow the Id content in the CalendarID field has been removed:
Is there some hidden error that is causing the Update item field value to be removed?
