Hi there, we're using O365 with ATP1, unfortunately recently got spams came in, in which on screen the text are normal english, but when copy & paste to notepad, there are special/hidden characters in between the normal readable characters.
Actually if simply search "Office" it couldn't search anything, that's why my regular expression filter didn't work.
I'd like to use regular expression (or any other workable method) to filter this kind of spams, any idea how to do?
Should you need more info, I'm available to further discuss with you. Many thx!
