Is Microsoft Word 2010's “encrypt with password” secure?

I have heard that security in earlier versions of word was not robust.

With Word 2010, if I use the File > Info > Protect Document > Encrypt with Password option, is this a secure way to protect a file?

Or is it trivial to crack the security provided by this option?

Update: its easy to crack. A couple of my co-workers did it in an hour with some tools – Ken Shaw Jun 7 '11 at 17:47

Ken would you be willing to self-answer your question, mentioning what tools they used? – nhinkle♦ Oct 28 '11 at 17:04
