Unfortunately the Excel connectors make you select a file using the file picker and you can't use a dynamic path which would include the prefix. I also tried being clever and made the Flow create a new file each time with a stripped down UtcNow() expression as a prefix. I even removed the folder permissions in SharePoint for the account that runs the flow and SharePoint/Flow still thinks it has it open. The other two would fail with Error 423.Ĭurrently the Flow is failing every time with 423 and the file has been locked for over 24 hours.
The log shows consistent successful flows until this date, and then it is only successful once every couple of hours. I keep getting error 423 locked by user in a flow since Aug 31 5:13am.
