Office 365 Exchange Online - Exchange Online Protection - How to filter out display name attacks?
Hi,
Users are receiving SPAM mail where the display name is of our CEO, but the "from" email address is not the CEO's, it's some other external address.
How can I add in a filter to EOP to delete any incoming mail with a display name of the CEO which does not use the CEO's exact email address?
Thanks

Thanks, I've setup a transport rule to block external email from our domain.
Try to analyse the headers and check the senders IP address and block it using rule in office 365 portal...
