I've deleted accidentally the automatic certificate that exchange 2007 creates in IIS 7.0 configuration. Now, I can't access to OWA using http and https. How can I recover that certificate?
I've installed Verisign certificate and when I acces owa inside and outside my network, it appears message "HTTP Error 503. The service is unavailable"
In event viewer, appears event id 15301.
Is the certificate generated automatically necessary for echange validation?
