Access is denied while connecting to OWA from inside the network.

OWA is running on the exchange server allowing external users to authenticate with mail.domainname.com which is then routed to an internal addres via the firewall.  We have our own DNS server so anyone accessing OWA internally points directly to the internal address through local DNS.

The problem is that when any machine that is not a local domain member attempts to access the URL internally, the authentication box continually pops up and will eventually give "access is denied"

Does it make any difference if they log on as DOMAIN\USERNAME , instead of just USERNAME ?  Or did you already try that?

Users login with user@domainname.com. If the PC is part of the domain, no issues.

This worked for the non-domain members but then everyone else lost the use of spellcheck. Apparently, this functionality is tied to authentication in OWA.

What is the actual purpose of the "integrated authentication" ?

pcfreakerCommented:
The main purpose is to authenticate the use of authorized user accounts via Active Directory with Integrated authentication, thats why the user needs to logon to a domain, the rest is via Basic Authentication...
