I found this SSL Diagnostic utility from Microsoft that explained that somehow the private key for the certificate was not present. &nbsp;I got the cert reissues and now all is well. &nbsp;Thanks!<br />

I have a new Windows Server 2003 SBS install with all the latest patches and Exchange SP2. &nbsp;I am able to reach <a href="https://FQDN/exchange" rel="ugc">https://FQDN/exchange</a>&nbsp;with the default certificate the server made (webserver.domain.org) however when I replace that one with one published by RapidSSL (mail.domain.org) I get 'CANNOT DISPLAY THIS WEBPAGE'. &nbsp;This persists internally as well when I try to access <a href="https://IPADDRESS/exchange" rel="ugc">https://IPADDRESS/exchange</a>.<br />
<br />
I have recently installed two other SBS servers with the same process (I thought) however this one is kicking my butt... &nbsp;As always, your help is very appreciated.

Applying 'real' certificate makes OWA inaccessible?

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.
