I would delete the afffected user mail profile (and OST file), and re-
create it (re connect to Exchange Server). Hopefully it'll fix it.

Duncan,
Thanks for the advive about the SBS analyser, I'd been using the exchange
server analyser, the OWA/Vista problems are now fixed but Outlook 2003
still refuses to send mail from one affected account - messages appear to go
but never arrive. same account but via OWA is OK.

Cheers

Ron

Have you installed the Vista compatibility patches for both the Vista
clients and SBS?

Download and run the SBS Best Practices Analyzer tool and fix all the
problems it finds.

Hello, I wonder if anyone can guide me on this problem..

I have a client with an SBS2003 setup As far as i can tell it is pretty
much
' straight out of the box' at least that is how I'm told it was set up a
few
years ago. Normally, It sends and receives mail via SMTP with all the MX
records pointing to it.
Recently, one of the not so tech guys that work there tried to set up a
couple of Vista business PCs and that was when the trouble started.
At first, they could send but not receive, then I investigated the bounce
messages and determined that the 5.1.4 error code was referring to a
double
entered SMTP address. i was dubious, but did find that somehow the
address
was in two accounts, so on removing one copy, the mails started arriving
from that account. I tried re entering the same account and as expected,
the
user properties (email addresses) screen refused to allow the double
entry
as I'd expected it to.
What is weird is the outbound mails from that account then stopped! - but
only from outlook. if i log on remotely using remote web workplace and
use
OWA, all is fine.

As a side issue, OWA on a Vista client seems to hang when sending
Infuriating and apparently illogical
any ideas on how to proceed ?
