I'm unable to save a outlook calendar as a webpage from 2 different locations
using 2 different versions of Outlook & Windows.

1 machine is using Outlook 2003 on Windows XP, the other is Windows Vista
with Outlook 2007.

When I attempt to save as a webpage on the XP machine/Outlook 2003, I'm
continously prompted for a login/password to the website I'm publishing it
to.
On the Vista/2007 machine I go to save as a webpage, I'm prompted for the
login and password, I get a 'quick flash' of another small window, which
tells me an error has occurred, however it seems like it saves the calendar,
however when i look on the website, nothing has been saved.

On 3rd machine from a different location using Outlook 2003, I'm able to
save as a webpage without any problems. This tells me there is a problem with
the outlook setting in the first 2 machines. However, I can't seem to locate
where the setting may need to be changed.

Any suggestions?
