Greetings, Thanks for this response. I have not previously responded to this thread as it seemed focused on TREND product, which I have no experience with as we are EOP.
Like you I opened a ticket with EOP support but they were not very helpful with specifics. FWIW, MS EOP support did note late summer is prime time for spammers to hit EDU sites. EOP stats show very large increase in SPAM late July, but in our case, much is now being blocked and no longer even getting to user quarantine, which is what we want. Just my quick observations and a lot less calls to HELPDESK now.

Tickets open with both, and both acknowledge it but won’t say what the root cause is, just that they are aware of it and working to remedy it.

I was just sent the following that describes the latest threat (see below). It is exactly what we are seeing. Anyone else seeing the same? We're seeing many of them blocked, but many also getting through. Anyone using Trend IMSVA and getting most of these blocked? If so, how did you configure your filter to stop it?
