Zip files Exceedingly compressed size message of 30 megabytes are quarantined

I get this message when I received a zip file over 30 megabytes.

------------------

FILE QUARANTINED

The original contents of this file have been replaced with
this message because of its characteristics.
File name: '172-16-1-4-04SEP14.ZIP'
Malware name: 'Exceedingly compressed size'

-------------------

I have 3 question

1. How do I turn off the function in Exchange 2013 of blocking ZIPs over 30 megabytes?

2. Where is the "quarantine" located that the error message is referring to?

3. If I want to how can I raise the value to 50 megabytes?

Please do not post information about Forefront on this. This is not a Forefront problem
