OWA Not working Internally or Externally

Hi All,

For no apparent reason OWA has stopped working on one of my clients servers.  It's a single 2008 SBS Server and when I logged on to it today I can't get OWA working either internally or from the outside world just get "Internet Explorer cannot display the webpage" error.  IIS is running and there are no exclamation marks next to SBS Web Applications.  Have checked the web publishing log and got the following message:

The World Wide Web Publishing Service (WWW Service) did not register the URL prefix https://*:443/ for site 1. The necessary network binding may already be in use. The site has been disabled. The data field contains the error number.

Would really appreciate some diagnostic steps as it's causing the company huge issues.

Many thanks for your help

Fix the issues it flags and check after a restart.
Get back to me if still no joy after that.

Please re-run the Fix My Network Wizard and test again.

Scans your site and returns information about your SSL implementation and certificate. Helpful for debugging and validating your SSL configuration.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

Can you open the owa interface by using the internal ip address of the email server?  Try using https://192.168.1.xx/owa (use your ip address) and see if you get the sign in screen.  If you do, then it's a dns issue, if you don't then we may need to look elsewhere. (possibly the host file on the server).

Hope this helps!

Just ran the internet wizard on the server and it stops with an error saying:

Internet connection is incomplete

Windows SBS did not properly configure your e-mail.  To correct this, re-run this wizard.

I've re-run the wizard but the error just comes back.

Thanks for your help, BPA highlighted a whole host of issues but the specific problem I had was to do with port 80 bindings on default and sbs web apps in IIS. Removed 80 on SBS Web apps bindings and selected the correct cert and everything came back!
