I have an ISA 2004 firewall proxy in my network. I can use the internet throught this server. But when I access any external mail server using OWA, it connect to the server and ask for logon credential. Even if I mark remember password still the popup keeps on coming. I can see the details of Mailbox on left pane but the mails are not readable.
I applied all protocl access to internal to external and external to internal, still the issue remains…Any suggestion please…
