Exchange 2007 ISA 2006 and ActiveSync 1

[Divaldo]

We are trying to get Exchange 2007 ActiveSync to work externally through ISA 2006 so people can access their info from mobile devices such as iPhones.

We've installed it using Verisign SSL certificates and OWA works fine. I can't however get ActiveSync to work. I've tested in on

The problem is definitely with the ISA config. Two thirds of the way through this page it starts describing how ActiveSync needs to be set up with ISA:

http://www.isaserver.org/tutorials/...tiveSync-RPCHTTP-2006-ISA-Firewall-Part6.html

Follow the ActiveSync section and into the next chapter of the article and make sure that all your settings line up.

Thanks for your reply, I altered the ISA config to be NTLM authentication and then in IIS on Exchange set it up as integrated windows authentication and it all sprung into life!

Hooray!
