I have read on so many sites that a docx document created in Word 2013 will open in Word 2010. Well, it will open but the formatting will NOT be maintained in exact form. If anyone would like to help out with this issue please reply to this discussion. I have documents that must be used by many different companies and all of them do not have Office 2013, in fact most of them either have Office 2007 or Office 2010 with just a very few now have upgraded to Office 2013.
The documents we create are very complex in nature with many drawings, graphics, tables and, text boxes as well as using 2 column formatting for textual content.
