I have a slight problem with a couple of Outlook 2007 users (Exchange 2007
account).

When they launch Outlook, a box pops up headed "Connecting to sites",
prompting them for a username and password. I have no idea what this is
about (their domain username and password don't work, so I'm guessing it has
nothing to do with Exchange).

If they dismiss the box, they can then continue as normal.
