Hopefully this has a simple fix.

When right clicking on my calendar in Outlook 2007, I chose the "Publish to
Internet"/"Publish to Office Online" it takes me to the screen where you are
introduced to Microsoft Online REgistraiton to Office Online - with the
yellow themed bars across the top and bottom. I am given the choice of 'Next'
or 'Cancel'.

I chose 'Next' and I am consistently presented with the grey error dialog
box which reads "The Microsoft Office Online registraiton page cannot be
accessed. You must first register before you can publish calendars to Office
Online. please verify that your computer can connect to the internet, and
then try again".

Obviously I have access (otherwise I couldn't pose this question) and I have
logged onto office online in a seperate browser window with no problem. (Both
during my attempt and before/after with same success.) I have disabled my
firewalls (ZoneAlarm and Windows) and nothing seems to work.

I know how to do this successfully, for I walked my co-worker through the
process with his installation without a single problem.

Any thoughts?
