I have a new exchange 2010 sever i added to a domain. I inherited this site without knowing some things.
The old exchange 2003 server was working fine.
I built the new exchange server with a domain name of olddomain.com for internal use, and they use newdomian.com for external email.
I did not know that this site no longer owns olddomain.com so when i requested a UCC certificate from Godaddy they were unable to put server3.olddomain.com on it because we didnt own the old domain. So now when the cleints login they receive a certificate warning " server03.oldomian.com is not the name on the certificate "
They click ok and everything is fine, however it is annoying.
I tried removing the UCC cert and re-issue a self signed cert and assign it to SMTP, then re-import the UCC cert and give it IMAP, IIS, POP but not SMTP.
However SMTP keeps popping into the assigned services.
I have looked at the knowledge based articles regarding self-signed / dual honing NIC's etc etc. and none seem to apply to my situation.
I need to have the Godaddy cert for the iphones etc and they will not add the server03.olddomain.com to it.
I have trie dthe redirect :
Set-ClientAccessServer -Identity <ClientAccessServerIdParameter> [-AutoDiscoverServiceInternalUri <Uri>] [-AutoDiscoverSiteScope <MultiValuedProperty>] [-DomainController <Fqdn>]
I have set all the Virtual directories etc.
My question is, within EMC, the HUB transport tab - Receive connectors - Default connector there is a field " Specify the FQDN in response to EHLO " this currently conatins the Server03.oldomain.com " if i change it to " Mail.newdomain.com " will this solve my issue without breaking anything?
Thanks in Advance
