Hi,

I've actually got quite a funny problem. I'm running Exchange 2007 with ISA 2006 doing my OWA Web Publishing for Internet-based connections. It seems to be working fine as I can access it from any internet based computers on IE, Opera, Safari and other Web Explorers as well.

From PDAs and only on Windows Mobile based PDAs, I cannot log in to the OWA site via the https://webmail.domain.com/owa link. The error that I get is:

Code: 401 Unauthorized. The server requires authentication to fulfill the request. Access to the Web Server is denied. Contact the server administrator. (12209)

However, from the same Windows Mobile based PDAs, if I use Opera to browse to the site, it works fine. Any suggestion guys cause I'm stumped.

Thanks in advance.

Watch Question

do you have site certificates loaded that need to be copied into the phone?
Hi,
In the ISA Server MMC
- on the left side
- go to the properties of the server / array
- go to the "Incoming Web Requests" Tab
- uncheck the box "Ask unauthenticated users for identification"

Thanks,
SAM

Hi Sam,

The solution which you provided was actually applicable to ISA Server 2000 only. I've already seen the MS article which you were looking at. As I'm running ISA Server 2006, the Incoming Web Request tab isn't even there.
