Hi, I'm looking into upgrading to Exchange 2007, but I have a quaestion regarding owa on 2007. I plan to install exchnage on a failover cluster running win server 2003 enterprise64bit, but would like to install the front ent owa of exchange 2007 on an nlb cluster running win 2003 server standard 32 bit. Is this possible, or does the owa also have to be installed on 64bit servers? Thank you

Hi, OWA is an inseparable part of the CAS server role. All exchange 2007 roles must be installed on 64 bits OS. CAS servers can be NLB'ed Leif

Thank you for the information. I guess, what I'm asking is can CAS be install on 32bit platforms? SA
