How to point my MX records to Windows Live?
The MX record is listed under MX Record Configuration and should be similar to the one below:
DNS Record Type: MX
MX server: 442368421.pamx1.hotmail.com
TTL: 3600 or 1 hour
Priority: 0 (or High priority)
Then all you need to do is point your MX record to that of Windows Live and allow a few hours for the DNS change to propagate.
