Of course I do and I expect my employees to report such incidents to IT. Such documents are common attack vectors.
In my experience, customers are not aware of failing interoperability or possible security threats and often grateful for such hints.
There’s a reason why libreoffice (and I guess other office suits aswell), evince or antivirus show a big, fat warning when opening such documents. Surely there are cases were macros are useful or necessary, but if they have to leave the company, you’re doing it wrong.
