Cannot send emails

[brelade]

I am running Outlook 2007 on Vista, my ISP is British Telecom (UK)
I am unable to send any emails, I can recieve emails, in the bottom menu bar
an icon appears when I hover over it states: (Micrsoft Outlook is
synchronizing folders).
I also recieve error: 0x8004210b operation timed out waiting for a response
from SMTP server.
I have tried changing SMTP from 25 to 587 no joy.
I have tried extending timed out time.
Any Advice greatfuly recieved.

Kathleen.
Thank you for your reply.
In the end it was changing SMTP from 25 to 587.
BT have said that there is a temporary problem with there server and Vista,
port 25 at present is not working and as a temporary mesure they are using
port 587 until port 25 is fixed which they expect to be in a few weeks.
They say that port 25 is the main port for the server, and to keep trying to
change back over the next few weeks, as 587 is really not the correct port if
you know what i mean.
I imagine this subject will come up again when the correct server is back on
line.
Again many thanks for your advice
Cheers
