I've been through plenty of possible similar problems on here, but haven't yet found anyone describing what we're experiencing, so thought I'd ask my first question..! We have an Exchange server setup (Windows 20003 Small Business server, a single server) which we as staff access externally using Outlook Web Access. It works OK inside the domain, but from the web, the login page appears fine, and we can authenticate successfully, but it usually takes several refreshes (or close window/reopen) before the contents of the page appear. Even then, it's generally just the inbox panel; the navigation bar on the left doesn't generally appear. The speed of things appear is random; sometimes it's quite quick, other times it can take a few seconds, still more often, things don't appear at all. I have checked all the security permissions; all are as they should be. IIS is working fine - other pages hosted on the server appear instantly without any problems; OMA works fine from my handheld, it seems to be just OWA. Any suggestions?!
