I have Vista Beta 3 and Outlook 2007. I can send and receive with one
account, but my second account times out when receiving with error
0X8004210a. The test account settings works fine and it sends. But then
when I click Send/Receive it times out.

I checked the settings. They work fine on an XP Pro computer with Outlook
2003 on the same network.

I increased the server timeout as well.

I disabled all security etc.

I have no antivirus (yet)

I cannot even get to the webmail site to check that way. It pings ok, but
just continues loading when I try and go there.

Any ideas.
