Load balance Autodiscover with multiple CAS servers.

Not open for further replies.


I have 4 seperate Exchange 2010 CAS server installed in same SITE, how do i load balance the autodiscover url among the fours CAS servers?

I have no idea..

Do you have a CAS array and some form of load balancing set up?

That is how we do it (using NLB which is apparently not encouraged anymore)

CAS Arrays do not need to be configured to load balance AutoD, OWA, EAS, OLA. CAS Arrays are only used for MAPI connectivity.

For Autodiscover you would configure a load balancer across your CAS servers (which is not the same as a CAS Array), and then using Set-ClientAccessServer you set the AutoDiscoverServiceInternalUri values to the load balanced FQDN.

Set-ClientAccessServer sets the SCP value.


Set-ClientAccessServer <servername> -AutoDiscoverServiceInternalUri https://autodiscover.contoso.com/autodiscover/autodiscover.xml
