I have a flow which sends an email notificationt to a list of emails each time that an email arrives to a Outlook 365 mailbox from a specific sender with a specific keyword in subject. The flow has been running without fail since I created it a week ago. However, this morning it "missed" one of the messages. Three messages came in that met the criteria at the following times: 7:15, 7:27, and 8:35. The flow ran successfully for the 7:15 and 8:35 messages but it did not run for the 7:27 message. There was no failure in the history, it just did not trigger.
I thought that the issue might be that the messages came too close together in time but on October 4th, the flow triggered at 9:38 AM and then again at 9:46 AM. Also, we should have the "Flow for Office 365" which allows flows to run with a frequency of 5 minutes.
Any idea why this flow would fail to trigger?
