the problem with ISA 2004 is that it does not support SAN or UCC certificate and that is why it will not work with exchange 2010 if the latter use UCC or SAN certificate which is almost always the case

Its being passed through the firewall now, but permissions error 403 shows its ugly head when I try to connect to OWA log on page.

Could it be IIS 7.0 permisions?

you need to configure authentication on  IIS for OWA.

Enable windows authentication and add the NTLM provider.

Suliman Abu KharroubIT Consultant Commented:
Please confirm that OWA works fine internally.. to be sure that the problem on ISA server.

if it works internally , please make sure from the following settings:

1. Users tap on OWA publish rule contains "all authenticated users"
2. Authentication tab on the listener configured to use "HTMLform authentication"
2. authentication delegation tab on the rule configured to use NTLM authentication.

Internally, Yes it works. The problem is on the outside.

We are using a ISA 2004 FW, I dont see all this prompts you listed.

open the properties for the OWA web listener ( right click on the rule -->properties --> listener tab). then you can select the "HTML form authentication".

now, right click on the rule -->properties -->authentication delegation tab. and select NTLM.

The properties -->authentication delegation tab. and select NTLM and HTML form authentication do not exist in ISA 2004. I you talking about ISA 2006?

Suliman Abu KharroubIT Consultant Commented:
sorry for misunderstanding,

yes it is for ISA 2006.

but you can use windows authentication on ISA 2004:

Exchange OWA 2003 works.

I am trying to get OWA to work on Exchange 2010, when I logon to Exchange 2010 OWA, it brings me over to a Exchange 2003 logon screen.

I am setup for Forms authentications, I point the rules to the new Exchange 2010 Server and create dns names.

Any Clue.

do you mean that you have another exchange 2003 on network and ISA brings OWA 2003 instead of OWA 2010?

Network ITAuthor Commented:
Nope

When I logon to http://mail.domain/owa it brings up the Exchange 2010 OWA logon page. Now when I log on, it brings me over to the Exchange 2003 OWA logon page.  The user is on Exchange 2010.
