After upgrading to Microsoft Office 2010, would you stop saving and creating file documents with .doc and .xls format in the older version?
Did you convert the old formatted documents to the new open XML File format?
Office 2010 users who create or edit files in the Open XML format can convert the files to binary format by using the Save As command and selecting the appropriate 97-2003 format ( .doc, .ppt, or .xls).
Compatibility Checker will alert the users to any content in the file that is not supported by earlier versions of the application.
When a user uses the Save As command to convert a binary file to the Open XML format, the user has the option of selecting the Maintain compatibility with previous versions of Word check box. When users select this check box, the newly converted document is compatible with Word 2007.
Features that are exclusive to Word 2010 are disabled. The user then edits the document in Word 2007 compatibility mode.
When you enable this policy, the Maintain compatibility with previous versions of Word check box is selected and hidden, and Word 2010 will always save the file so that it is compatible with Word 2007.
