Hi, this one should be easy: I'm running exch 5.5 and 2000 in parallel. I have 5.5 OWA working fine, and 2000 OWA working fine. The problem is that I want to be able to access the mailboxes on the Exch 2000 server from the 5.5 OWA. According to MS and a few other sites, this is perfectly possible, but I get an error saying "The Microsoft Exchange Server is down or the HTTP Service has been disabled by an administrator. Please try your request again later" Please, tell me that it's just a matter of ticking a checkbox somewhere...
