Very interesting post by Kevin Reeuwijk here. I have been dabbling with Windows Server 2008 RTM and Exchange 2007 SP1 lately and had a single server install of Exchange on a rusty old dell laptop just for POC purposes. However, I did not run into the same issues with Outlook Anywhere that Kevin did, because I had disabled IPv6 right in the very beginning since I was trying to enhance the performance of my install on an ancient dell machine.

In other news, my Dell laptop finally managed to stop working. The NIC would misbehave and give itself a 169.XXX.XXX.XXX IP address for no reason. This led me to finally pony up the cash and sign-up for a hosted exchange account with Sherweb. So far the experience has been pretty good except for the initial setup when my domain's MX records had been configured correctly and propagated within the DNS and yet Sherweb's SMTP would refuse to accept my incoming emails with a 550 error. A quick call with tech-support resolved it in seconds ! Kudos to Sherweb !
