I have a dual boot configuration for my computer with WinXP SP2, and Vista
Business. I have Outlook 2007 installed on both.

I have e-mail accounts with COMCAST and the Exchange server at my employer.

1. With Outlook as the mail client on WinXP, and the COMCAST and Exchange
accounts set for POP3/SMTP, I have no problem connecting to the mail servers
and sending and receiving mail from both servers.

2. With Outlook as the mail client on VISTA and the same setup for the
COMCAST and Exchange accounts that I use in WinXP, the COMCAST account works
just fine, but the Exchange account does not. I get the following error:

Connection is interrupted. Error code: ox800CCC0F

If I click on the Test account settings button for the Exchange account, it
fails with the same error, but I can later find (in WinXP) that the test
message was successfully received through Exchange into my Inbox.

3. In VISTA, if I set up Windows Mail using the same settings that I do for
Outlook, it works fine with the Exchange account.

Thanks in advance for your help.
