We are planning on using TMG for this purpose. We did it in our lab, and it worked, but we had limited NICs, so we could only have either Activesync or OWA working at any one time. As long as you have separate NICs for those, you can set up multiple listeners, and you're set.
We're in the process of migrating everything that was coming in through iChain to our TMG/UAG environment. >>> "Stringham, Steven" <sstri...@lrlaw.com> 4/19/2011 2:54 PM >>> We presently have a Ex2003 environment. I am working on our Ex2010 world. My big holdup is OWA. Our present external proxy is an old Novell iChain proxy server. It works great with Ex2003 OWA. But, it sucks with Ex2010. I am testing the following as possible replacements: This needs to front my extranet for RSA securid, multiple internal web servers, etc. TMG 2010, UAG 2010, and Citrix Access Gateway. If I connect to my CAS array internally, OWA 2010 works great. No problems at all. It is when I go through a proxy that I I have not yet completed my testing with TMG or UAG. But, with iChain I can see the mailbox, (and sometimes it works great!), but I cannot open messages, create a message etc. It just freezes with javascript errors. I have seen some issues with this in Google, but no good solutions. With the Citrix Access Gateway 5.0, I can authenticate, and work with messages. But, when I try to delete or move a message in the list, it give me an error. (An unexpected error occurred and your request couldn't be handled. - and then the message remains) This also has a bunch of threads on the web, but the system work great internally. So, 1) has anyone gotten it to work with well with the Citrix Access Gateway? 2) Any other products recommendations to look at? 3) Any fixes for the errors discussed?
