Do you host this SBS2011 in your office or co-location? I always change the Naming Servers (NS) to the new Domain.

Hi Hkchris,

The link you sent is for POP3 Server, i.e if you are just using your hosting POP3/SMTP server to collect and receiving your email, but in this case there is SBS2011 Exchange 2010 being used.

Exchange doesn't care who the provider is.
You just need to ensure that any external DNS entries are pointing to the new IP address. That will be just the A record used for MX and possibly any other host names that are pointing to the old IP address.

If you have your external DNS with another provider and they support TTL time changes, turn the TTL time down to 3600, which will mean the internet will see the changes quicker. You need to do that at least 48 hours before the change. After 48 hours, change it back to the default.

Simon.
