Exchange flagging a single user's email as spam
Will_Wilkinson - you don't have a transport rule forcing that SCL 9?
If on-prem had the same bad habits as ATP, I'd be looking for a matching recipient name causing a false positive phishing detection.
ExMSW4319No transport rules that could force this - it's happening on not only the customer's system but on all exchange servers that this single e-mail address communicates with - have submitted samples to Microsoft, and, as a work around, set up another address for the user - this works normally, from the same server & client, just from a different mail address. Original was of the form mailto:initial.surname@company.de, new is mailto:firstname.lastname@company.de - weird thing is that all other users don't have any problems, and this single one does, even on a new build.
