Hi,

I rolled out an Exchange 2007 infrastructure about a year ago to
replace an Exchange 2003 infrastructure. While building and testing,
I used the OWA url of newwebmail.domain.com since my Exchange 2003
infrastructure was using webmail.domain.com. After I cut over, I
renamed the Exchange 2007 OWA internal and external URL's to
webmail.domain.com through the console, and I renamed the OWA, EWS,
Autodiscover, etc virtual directories to webmail.domain.com through
the shell (set-{virtualdirectory-url}). Everything appeared to be
working fine for quite a while. Clients were autodiscovering
services, OWA was working fine, and it appeared all the other virtual
directories were working fine as well.

In comes Lync. I only noticed this after Lync phones weren't able to
update Calendar information. I don't know if it's related, but it's
something I want to fix. If I'm in Outlook 2010 and go to the "File"
tab, it tells me to access my account on the web through
"newwebmail.domain.com". I was wondering where it got it from, so I
did a test-owaconnectivity from one of my cas servers, and it comes
back with newwebmail.domain.com.

I'm curious where that is coming from and how I can change it to the
correct URL? I'm hoping I don't need to have a DNS entry for
newwebmail and then add a forwarder server side. It seems a bit
limiting if this couldn't be changed. Thanks!
