OK who hosts your domain name? do a whois lookup you need to go to the person who managed your domains and tell them of the new IP change and get them to make the changes you then need to look on your firewall and change all records pointing to old ip to reflect the new ip
Which VPN tunnel do you use?
Do a MX lookup on your domain name for emails i.e @companymail.com
http://www.mxtoolbox.com/
You will see that it points to the old ip
Do the same for all other websites like owa etc and again they will point to the old ip, DNS and MX changes are not instant so you gotta start moving on this so the impact is not as big as your going to start loosing emails
no problem just give it sometime and check again
do a nslookup for the domain names and an mx lookup from time to time to see the changes you will be fine also please make sure your firewall rules reflect the new IP i.e. if your natting smtp connections for port 25 you need to make sure the rule on your firewall takes into effect the new public ip do the same for any other policies which show the old ip and you wont have any problems
normally DNS-records are cached for a day or (also seen up to three days)...so due to the "time to life (ttl)" it will last that long until other mail-servers ask for your actual ip from the MX-record. So the next time email-flow should start.
Do you get onto your email-server from outside when trying :
telnet <yourNewIp> 25
from your home-computer ?
You normally should get a line starting with "220...<your mailserver>...ready"
If this works does:
telnet <yourMXDomainName> 25
also work?

How are they accessing the servers? If you have been given a new static IP
You need to change MX, A records with the new IP if you use VPN tunnels you need to recreate the setup file to reflect the new ip
