How to test if working correctly

Hi all, So I am completely new to using load balancers and we have got a couple of F5 BIG-IP's for our exchange environment.   We are on version 11.5.3 and I have used the iApp template to setup o...

Hi, for OWA, do you have DNS record pointing to the virtual server IP? For Outlook, is Autodiscover returning the correct URL for clients to connect to, and is the DNS for that hostname correct as well?

 

Since you are in a lab, you should be able to easily see if any traffic is hitting the virtual server(s) you have configured for the Exchange services by looking at the virtual server statistics tab.

    Thanks for your reply. I have a CAS array with a DNS entry and IP address. The IP address of the CAS array points to the IP address I have given the virtual server. OWA on my CAS servers now points to the CAS Array address instead of the individual CAS servers. So for example I have autodiscover.domain.com and mail.domain.com in DNS. Both point to the IP of the virtual server. Autodiscover returns mail.domain.com as the url for Internal OWA, Exchange server for RPC protocol, EWS, OOF and OAB. (Including ecp) It all seems correct but I don't seem to be getting connection to the BIG-IP. All of this is on the same subnet so I am wondering if there is additional configuration required other then the iApp template and DNS changes.
