Outlook Express works, Outlook doesn't on only one XP system

[Sandy Tipper]

I have two XP client systems and my own Linux mail server.
The XP Pro system can use Outlook to access mail.
But the XP Home system can use Outlook Express but
not Outlook, although setup seems the same.
When sending a test message in Outlook, it finds the
server, but both send and receive fail, saying the server
didn't respond (check ports and SSL). Not using SSL, and
the ports are standard. What's more, Outlook Express
on the same client connects and works fine.
I've checked the DNS, the routing, ping, firewall, etc.
(XP firewall disabled, Linux firewall open to LAN.)
What's even weirder, Outlook used to work, but I had to
change all IP addresses on my LAN, now it doesn't work.
Any ideas? Could Outlook be broken (virus)?

Have you tried starting with a fresh mail profile?

Have you tried starting with a fresh mail profile?

Thanks for the idea, but it didn't work. Same error.

Did you ever get this working? I have a similar problem...
