I have 3 Exchange 2007 CAS server with 1 virtual directory.
The external URL is webmail.domaine.com
my COMODO certificate will expire soon and i need to add same new owa URL.
1-to add 2 new owa url, for exemple owa1.domaineA.com and owa2.domaineC.com, i just need to add this url to my certificate and redirect this new 2 url to the existing owa virtual directory or i need to create 2 new OWA virtual directory?
2-When i change the certificate in Cas server, i need to restart IIS service or not?
