OWA shows "cannot display the webpage" error

Hi,

I was about to migrate the users to a new Exchange 2007 SP1 installation, but I am encountering a problem accessing OWA. If I attempt to access the website from the http://localhost/owa it reports: "Error 403.4 - Forbidden: SSL is required to view this resource." If I then append the address to https it simply tells me that the web page cannot be displayed, there is no more detail than that.

The certificate is from a good CA, autodiscover works fine, there are no other web sites on this server and the host header for the site is blank.

I'm at a loss, I hope someone can help me shed some light on this.

You shoul dstart by resetting the virtual directoies by using the remove-owavirtualdirectory and new-owavirtualdirectory cmdlets.

Have you done it with all of the virtual directories?

no, only the OWA directory. Which ones really need re-creating?

Too many email signature changes to deal with?

Are you constantly being asked to update your organization's email signatures? Do they take up too much of your time? Wouldn't you love to be able to manage all signatures from one central location, easily design them and deploy them quickly to users. Well, you can!

I have fixed it. It was an issue with the certifictae not being installed correctly. I re-keyed the certificate with the CA and re-installed it. Subsiquently it works!

Does this error show up before or after the owa logon screen?

That was the problem, it wouldn't get that far as any SSL attempts even to a test page would not display, it was an SSL certificate error, not an Exchange Virtual Directory issue.
