Microsoft provides a compatibility pack which helps with exchanging files between Office 2007 / 2010 and previous versions of Office.
But it's not clear from the description whether this means that Word 2007 and Word 2010 are completely interoperable - i.e., Can Word 2007 read and edit files created in Word 2010?
3Office 2007 can only read a document provided it doesn't contain any specfic 2010 features. This of course is the case with any version of Word. – Ramhound – 2012-03-22T14:44:33.350
