I have stood up a new Exchange 2010 SP3 Server (VM) into an existing 2010 Standard Site. I need to go through the New Exchange Certificate Wizard and have a few questions.
On the wizard step below I am seeing the old server MSX (currently in production) listed with new server. Should I leave the old server "MSX" in the field below? Does it cause any issues to remove it and leave just the new server "MSX-V"? Not cutting over for a month or so.
Client Access server (Outlook Web App)
Domain name you use to access Outlook Web App internally.
Under the wizard step below the wizard double entered the domain name? Should txt in bold be removed?
Client Access Server (Web Services, Outlook Anywhere, and Autodiscover)
Outlook Anywhere is enabled
External host name for your organization (example: mail.contoso.com)
Under the wizard step below it is populating the field with ourdomain.com shouldn't this be mail.ourdomain.com?
Hub Transport server
Use mutual TLS to help secure Internet mail.
I am looking at Digicert, Geotrust and Thawte for the UC SAN Certificate. Anyone have any issues with any of the three and is there any consensus on which one is best?
