Hi,
Setup:
3 CAS servers - Exchange 2010
1 IIS ARR reverse proxy
I followed these two 1 2 write-ups on how to setup Exchange 2010 OWA to use IIS ARR as a reverse proxy. The problem I'm having is when all three servers are online in the server farm OWA doesn't work properly. You can log in fine, but it appears to not load fully and you can't click on anything (eg Calendar, emails, forward, reply, etc). If I were to take all the servers offline except for one (doesn't matter which one), OWA functions normally.
Since some users also access OWA internally I have configured IIS on each CAS server to redirect to HTTPS and the OWA virtual directoy. I don't think this is causing the problem, but I thought I should mention it.
I followed the articles exactly. I'm not sure what could be causing the problem.
Thanks
