Yes its a bug.
There is a feature that has been used in the HTTP interface to msnews that
is being incorporated into NNTP with WinMail, exclusive to the msnews
server. See here for details:

Unfortunately they not only didn't provide any documentation on this in
the help or anywhere else in WinMail but they also released it with a
bugs. If you sign on with your Passport or LiveID or whatever they are
calling it now, then you will see the new community features. To do this
though you get the error originally referenced in this thread. If you
close those error windows after signing on, then you will able to see the
ratings and such and be able to rate the messages.
Unfortunately as per usual with Microsoft in reference to its OS mail
programs, they dropped the ball again and didn't bother to tell anyone
about it, and they released it with these bugs that they knew existed.
As others indicated, you can right click on the MS Communities in the
folder list and go to Properties and Windows Live ID and disable the
communities feature if you wish.
It was a really nice feature set to add to WinMail, but it will probably
fail now because of the bugs and lack of support by MS.
