My company is using fully patched XP machines (SP3 plus all the critical
updates.) We are sharing calendars using the "Publish to Office Online" with
outlook 2007, fully patched. We all created Windows Live IDs for this
purpose and some of us are now getting the error:

“Access to the resource was denied. If you have signed in to and saved
your Windows Live ID with a Web site, sign out of that Web site, and
then try this operation again.�

I have logged out of messenger and any online website that I was aware
that I had POSSIBLY signed into using my Windows Live ID and I still
get the error.

(Even if that was a workaround, it is ridiculous.)

An internet poster mentioned the C:\Documents and Settings\[your
username]\Local Settings\Temporary Internet Files directory. I assume
that there are certain files to be deleted in there? I blew all of
mine away just now and will see if that fixes it. I would prefer to
know which file in particular should be deleted so I can create a
little script for people to run to fix this issue when it pops up
again.

The only article Microsoft has published is Vista-specific.

Any word on when this will be fixed? You TOUT this as a big feature and it
just plain doesn't work.

I am experiencing the same problem. I deleted the shared calendar in Outlook
(I was not aware of having published it and do not use Office Online).

This did not resolve the problem.
