I've read various articles about Microsoft's Office 2007 encryption and from what I gather 2007 is secure using all default options due to it using AES, and 2000 and 2003 can be configured secure by changing the default algorithm to AES. I was wondering if anyone else has read any other articles or know of any specific vulnerabilities involved with how they implement the encryption. I would like to be able to tell users that they can use this to send semi-sensitive documents as long as they use AES and a strong password. Thanks for the information.
How secure is the encryption used by Microsoft Office 2007

Yes office encryption is pretty secure. I put together a presentation on office 2007 security a while back. Here are the relevent bits from a whitepaper I referenced.
