Unable to connect Outlook 2007 to Exchange under Vista

[Guest]

Hi,

Been using Off2007 with XP clients for some time without issues. Right now
i'm doing a Vista valuation and seeing this error message everytime i try to
connect to the Exchange server (2003)

'Unable to logon to Exchange server....'

I have gone through all network settings and made sure they are set equally
to the rest of my XP clients, but no luck. The Vista client is working
flawlessly in all other aspects. I have tried setting up an IMAP account and
that works well.

I can ping the server with all FQDN and just simple NB name. I have read all
kinds of articles but still haven't nailed it.

Any ideas, this process has taken way much time already...

Best regards,

Eirik Alim

Just to add up,

I have tried to disable all secutity software (Symantec Endp Prot) and
Windows FW & Defender.

The client is in the LAN so no HTTP/RPC case.
