A few months ago we changed ISP's and therefore got new IP addresses. When i try to go to our Outlook Web Access from outside the business it is resolving to the old address. So if our url to outlook web access was
that is taking me to http://uuu.xxx.yyy.zzz/exchange
is our old IP.
if i ping owa.somecomp.com the ping resolves to the correct new IP
if i go to http://aaa.bbb.ccc.ddd/exchange
where aaa.bbb.ccc.ddd is the new ip OWA comes up fine.
Seems like something was missed in the conversion just not sure what
