Currently running Exchange 2010RC with 2008R2. Have configured OWA and can access mailbox successfully internally (LAN) and externally (WAN). Also using Full Outlook (2007) internally (LAN)
Internal URL is https://ben.teton.wibbleword.com/owa
External URL is https://secure.wibbeword.com/owa
Currently trying out a "new" SSL certificate (issued by valid signing authority) for secure.wibbleword.com
Have imported new SSL Cert into IIS7
When I change the bindings for site within IIS7 to assign port 443 from default certicate created when installing Exchange to "new" SSL certificate the former security warning (name not matching certificate) when using OWA externally is no longer displayed (expected). However now when using Full Outlook Client internally am now receiving security warning about name not matching - it's expecting ben.teton.wibbleword.com (the original cert)
As far as I can see I can only bind one certificate to port 443 - is there any way around this so I can negate security warnings when accessing Exchange from both LAN and WAN ?
