Hi,

I'm moving our environment from a single instance of Exchange to two new Exchange servers with a load balancer in front of them.  I have followed Microsoft's article here and also the load balancer manufacturers setup here.  This works for the most part but I'm having trouble with owa site.

Previously in my single Exchange setup when a user would put in mail.mydomain.com it would auto direct to https://mail.mydomain.com/owa/auth/logon.aspx?replaceCurrent=1&url=https%3a%2f%2fmail.mydomain.com%2fowa%2f which is what I want it to do.  But now with the load balanced setup and putting in the same mail.mydomain.com it just goes directly to the default IIS page.

I have tried doing an HTTP redirect in IIS on both servers pointing it to https://mail.mydomain.com/owa but when attempting to login to the owa but it just returns to the login page causing some sort of loop.  It works fine when I'm using localhost.

What can I put in place to make it redirect like it use to?

Hi timestream,

Thank you for your question.

By my understanding, when we create A record which is mail.mydomain.com, it should point to the Virtual IP which have been referred in Barracuda Load balancer.

Then we could make sure there is no redirection in OWA virtual directory on two Exchange CAS servers, then check if the issue persist.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim

Hi Jim,

I have already done both of these things.  I've changed my original post slightly to make it more clear what I'm asking for.
