Some of our users which own a Blackberry and are using the Blackberry Internet Service (BIS) have recently been experencing issues whereby the email stopped working after moving Exchange 2007 OWA though an ISA 2006 R2 Firewall.
When the ISA Server was connecting to the IIS Server it uses Basic Authentication, this all worked fine when using OWA directly over the internet, however BIS still failed.
Looking more closely at the traffic from the BIS Service it was trying to connect to the the following folder and file EWSexchange.asmx. Reviewing the IIS settings only windows auth was selected after selecting Basicm, all started working.
EWS (Exchange Web Services), is the main web service used by Exchange, developers can use the Web Service to access the Exchange services. one of the main components which use this web service is the availability service.

You can set up ISA 2006 to use FBA on the ISA with BIS. I have answered this and explained how to set it up here and verfied by a second source http://supportforums.blackberry.com/t5/BlackBerry-Internet-Service/BIS-ISA-2006-OWA/td-p/296761/page/4

No problem. I have now wrote a proper guide for it here

Your guide comes very close to helping us but (probably an SP difference) our ISA tabs are different.
The main problem is that the comments you mention “at the end of the guide” for ISA servers not in the domain are not there. Please tell me where I can find those as it is a crucial difference.
thx

The above guides are no longer available. I have moved them to my blog here:
