I think you need to have another Exchange server so you can do what you want to do. FE and BE. The FE sits on your DMZ while the BE sits on your internal network. Otherwise you need to move your single exchange box to the internet network and setup SMTP publishing rules on your PIX for it. OWA is a different story since it doesn't use port 25, and uses port 80 though I think most will agree that you use OWA with SSL instead.

Ok seems to be a local issue. What security setting is your IE set to? Try lowering the security setting to medium low, click reset and try again. ________________________________ From: Kerry Takenaga [mailto:kerryaku@xxxxxxxxx] Sent: Fri 12/16/2005 6:55 PM To: [ExchangeList] Subject: [exchangelist] re: OWA trouble in view e-mails http://www.MSExchange.org/ Thanks -my settings on IIS exchange was already set to anonymous. In addition I turned off the explorer pop up blockers as well as the Norton Security. I can log into OWA but still only see the top and left tab (icons/text) but NO Emails. If I switch to another computer I can login and view my emails. Any other fixes? Please.
