Hello,

This morning I was notified that the 'Send an email' action within the 'Office 365 Outlook' connector is safer to use than the 'Send an email' action within the 'Mail' connector. As a result, I have been instructed to go through all of my Flows and change the connector for any Flows that send an email. I can't find any differences online as to what makes the 'Office 365 Outlook' connector safer. Does anyone know anything about this?

Thank you

Hello @Breaker_ ,
it's safer if you're sending a lot of emails. 'Send an email notification' action using the 'Mail' connector has limit of 100 emails per 24 hours. 'Send an email' action using the Outlook connector can send 900 emails per 60 seconds.
You can find a few other limitations in the Microsoft article on the Mail connector: https://docs.microsoft.com/en-us/connectors/sendmail/#send-an-email-notification-(v3)
