The SSL for OWA (exchange 2007) expires in a few weeks; I was wondering while waiting for the process and activationof the new SSL will the server be down? Thanks

No the server will not be down and this is how you do it on IIS 6Find your "Default Website", right-click on it, and select Properties. Under the "Directory Security" tab, click the "Server Certificate" button, then click "Next" on the wizard welcome screen and select "Renew the current certificate"Raj

Thanks Raj.If I use the shell command is it different from IIS?I appreciate it.

No, the result that you will get from GUI and Shell will be same.Raj

thanks Raj.
