10.0.0.0/8 is a private range, that you can use as you please for private networks, including 10.0.0.0/24.
20.20.0.0/24 is:

schaefer@reliant:~$ whois 20.20.0.0   

NetRange:       20.0.0.0 - 20.31.255.255

This will work, as long as you have a NAT between those addresses and Internet,
and obviously you won't be able to contact any of those Microsoft IPs anymore,

In short: bad idea. Use private ranges only (or any public range that you own).

Parse error.
