"ErrorQuotaExceeded"

I am having a problem about an alleged “excess” in my quota. But I’m far from reaching my limit, as you can see in the image. If anyone knows what could be the origin of this problem, I would appreciate the help.
It´s a outlook 365 integration.


Isn’t that message coming from the 365 Server?
Are you sure you haven’t exceeded a quota on that side? Maybe a message sending limit or something like that?

Hi Darren, it was indeed due to a limit on the Outlook 365 account. Thank you for your response.
