I am not a lawyer, and so I cannot give a legal opinion.
If you were to use artwork from the Microsoft Office Online site as part of
the cover for your book, that would appear to be allowed under that
agreement.
However you really should run that past your lawyer, who needs to read the
entire agreement, because you will note towards the bottom that Microsoft
retains the copyright over everything and reserves all rights under that
copyright. It's quite a minefield, and is subject to varying interpretation
based upon the jurisdiction into which you enter the contract.
And that agreement applies ONLY to the artwork made available to you as part
of the Microsoft Online Service. It does NOT apply to "clipart" on your
computer, and it does NOT apply to the clipart offered by Microsoft Partner
Companies that use the Microsoft Office Online website as a shop window in
which to display their wares for sale by themselves.
I think most authors would simply "change" the artwork sufficiently to turn
it into a "new work". That would ordinarily void the copyright.
Other people would "Assume it is OK" and go ahead, relying on the rule that
by the time they have sold enough to be worth suing, they will have made
enough money to pay the penalty. Of course, you could not use that strategy
if you are not self-publishing: a commercial publisher will expect you to
obtain a release for anything you use.
Sorry: You need a lawyer, not an MVP, to answer this one
Cheers
How about the clip art from Microsoft Office Online? If I'm reading the user
agreement correctly, it seems that in my case (using the clip art for a book
cover) would be okay. True?
