Hi, I am running exchange server 2003 and started having some problem with OWA; when I try to access OWA from outside it opens up but I can only access the Inbox. If I click on the contacts or calendar nothing displays. Also I cannot access any folder within Inbox; this problem is only when I use IE but if I use Fire Fox then I can access everything but it prompt fro the credentials again for the second time when I click on the contacts or calendar . OWA works fine when I access it from within our network by http://mailservername/ for any browser. I am using ISA server to publish the OWA in the front end; I appreciate if anyone can help me to resolve this issue. Thanks Ven S
