A colleague's computer is not collecting emails from her ISP (TalkTalk in
the UK, if it's relevant). She has an old laptop running Outlook 2000,
which is set to leave messages on the server. When she picks up messages
from the old laptop, she gets all the emails, but if she does the same with
the new laptop, she gets nothing.

We've tried leaving the old laptop switched off and sending test messages to
this email account, but it's not being picked up, even though it shows up on
the ISP's webmail account and www.mail2web.com.

We tried deleting the account information and recreating it, and the 'Test
Settings' option worked fine. We were able to collect all the outstanding
emails, but after a couple of hours it stopped collecting them again, so
we're back to square one. My thinking is that the only option now is to
uninstall Outlook and start over, but I'm not sure whether this will
actually remove the relevant files from the computer.

Is this a known issue, and does anyone have any suggestions as to what I
might try next?

Thanks in advance.
