Has anyone experienced email throttling from Microsoft?

I'm building a new flow that worked fine on Friday, but won't send the emails today. The flow says it has succeeded, with no errors, but there are no emails. Also no emails from another flow that's older and has always worked fine. I changed my network password Friday afternoon, but I have made a new Outlook connection today, and I'm not getting any connection errors. I found an old topic on the MS Power Automate community that said “I think the high usage on the user-end in combination with the system issue causing dozens of emails to be sent in one go this morning (my time) caused this issue. It has just needed some very patient retriggering from the back end thank goodness.”

Has anyone else experienced this ever? or today?

Hi Susan- I think we need more information about the flow, is it gift related, constituent related? How many emails are you expecting that it might produce?

@Susan Walters
ask your IT team to do message tracing to see if email is being blocked on your email provider end.
