Outlook node misses Emails

Questions
1

I’m currently building a workflow, triggered by the Microsoft Outlook node. It is set at a 1 minute polling time, to ensure it processes requests as quickly as possible.
Sometimes, the connected email is receiving multiple messages at once. If that’s the case, only one’s being processed for some reason. In my understanding, the Outlook node should (once it’s triggered every minute), then process all new emails received during that minute and then process them simultaneously (I have 5 concurrent executions on my plan). But it only processes the first one received.
