When I log into Outlook Web App I can login OK But if I then close a tab and in the same browser reopen in a new tab it fails to load correctly (See image below), now this only happens when I log into the external Webmail address and not the internal or server address? Internet https://mail.company.com/owa - Issue Intranet https://LoadBalancer.company.net/owa - Working https://Server.company.net/owa - Working Workaround: I have to close all browser windows (So no iexplorer.exe is running on the PC) then log back in... I have tested this on the following browsers: - Internet Explorer 8,9, and 10 Firefox 12 All Image Place holders (Red X) point to: - https://mail.company.com/14.2.318.2/themes/resources/clear1x1.gif Technical Beta Tester || Matthew John Earley BSc (hons) || www.o0MattE0o.myby.co.uk

OK we do use Forrfront Treat Managment Gateway :) Its not easy getting the information out of my counterparts :D But will try and get them to add that rule in and see if it fixes the issue? Technical Beta Tester || Matthew John Earley BSc (hons) || www.o0MattE0o.myby.co.uk

Forefront is for the old system (Exchange 2003) F5 is for the new system (Exchange 2010) Technical Beta Tester || Matthew John Earley BSc (hons) || www.o0MattE0o.myby.co.uk
