SBS 2011/Exchange 2010 - error when accessing webmail from the internet

Hello experts,

I have sbs 2011/exchange 2010 running on a single box. There is a local ssl certificate installed and when I try to access webmail via https://webmail.mydomain.com/exchange I get the following error.

First i get the certrificate error (There is a problem with this website's security certificate) which is ok, when I click on (Continue to this website (not recommended), the below error comes up.

This was working ok before, but this error has started in the last few days. (the certificate error is not the problem, i know this is due to the local certifiacte, but the problem is i dont get the webmail login page)

___________________________________________________________________________________________________

Server Error in '/' Application.
--------------------------------------------------------------------------------

Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>
 

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

Normally you should access it through https://webmail.mydomain.com/owa and not /exchange
Did you configure configure any redirect recently ?
