Recovering failed hub&cas server - Exchange 2007 SP3 - Windows 2008 Standard SP2

I have two hub&cas servers (both roles are installed on each server), one server crashed and we are now relaying on other server only which is functional and no down time for the users as emails are flowing, since two servers were providing kind of load balancing hence we are rebuilding second server on the new hardware with the same name and configurations using "setup /m:RecoverServer"

After completing the setup and before doing post recovery steps e.g importing SSL certificate. User's outlook may automatically try to connect (autodiscover) to this server and outlook may through some errors until certificate is enabled.

Is there anyway to prevent outlook to connect to this server until it is fully recovered.

thanks

you can temporary isolate it by IP address so that it can see only the CA, and the server be unrea chable from clients

As soon as the server comes up, change the Autodiscover value.

set-clientaccessserver servername -AutodiscoverServiceInternalURI https://host.example.com/Autodiscover/Autodiscover.xml

where host.example.com is the name on the other server - match the entries. Then clients will be pointed to the other server for Autodiscover information.

It is a Powershell command that you can run on any Exchange server in the org. However you can only do that once the Exchange server you are recovering is up, so the setting can apply.

I am not sure what else I can explain that is more than what I have written.

Thanks Simon much appreciated, since there are other services to replace internalURi as well like web services, OAB etc. so we decided to import the ssl certificate quickly after rebuilt the server.
