I got some help and figured out how to alter a digitally signed Word document without using Word. I took the first paragraph of the post I'm replying to, signed it, and then changed "JanetK_CA" to "Janet". When I open the document, the signature is marked as invalid right in the signature block.
Here is a link to the invalid document on Dropbox:
