Top 5 External Senders?
I wish to find the best way (and alternative ways) to find out which external parties send the most email to users in my tenant. I cannot seem to find this straightforward and simple information ...
Hi Chris Morley
AFAIK, I don't think there is anything native to the Microsoft 365 admin portal that gives this currently. It is claimed in this support case but I can't personally claim or verify that

So, if it does great, if not there is a script here which you may be able to generate a report from the message trace logs -

In addition, many well known third party gateways, or 3rd party reporting tools would have this functionality. Just type in something like 'Office 365 Mail traffic reports'
Hope that answers your question
Best, Chris
