This is a curiosity question; we have a fix for the base issue.

Is there a way to set a mail flow rule that has a threshold that says if after a certain number of emails to the same mailbox are received in say 2 seconds, to block any new emails to that mailbox for a certain amount of time, and then would allow emails to that address to route as they normally would?

We have a mass email alert we send out on occasion, and usually get a couple hundred OOF messages. The issue is that the email address being sent from (this was fixed by setting up a no-reply@ mailbox) creates a service request for any emails sent to it.

    Hi Jon Mercer,

    Unfortunately, currently exchange online can't implement your needs, you can submit your ideas at the link below and let your colleagues vote for it. If your idea is very popular this can give Microsoft a better understanding of your needs. Thank you for your understanding.
