Exchange Anti-Malware and Trend Micro

Hellow,

I am finalizing an Exchange 2013 deployment and I have a question:

I have installed Trend Micro as the anti-virus solution for my exchange servers, but this is a file-level protection software, I guess it doesn't protect my Exchange, rather it protects only the windows server environment.

Should I enable the Exchange 2013 built-in anti-malware protection along with the trend micro? If it´s not recommended, which one should I choose to keep?

Thanks in advance.
