When setting up a simple Write to Excel Flow, everything works as expected if I send one mail message at a time. When I send multiple emails at the same time or really close together the flow fails with "Cannot write file to filesource." in the logs. The messages the I am going to track are coming from an automated source and may come in in groups of 3 or 4 messages at a time. I am sending to one drive and I stated no errors if I send test emails slowly.
