Change Office 2007 Default File Save Format

Microsoft Office 2007 (or 2007 Office System) uses a new XML based file formats and extensions for new documents, workbooks, spreadsheets or presentations that been created by Word 2007, Excel 2007 and PowerPoint 2007. These new file formats (in .docx, .xclx and .pptx extensions) are not backward-compatible, meaning older version of Office suites such as Office 2003, Office XP and Office 2000 cannot open and read the XML files. And by default, Office 2007 will save the document, workbook or presentation as new XML file format, which cannot be immediately opened or viewed or edited by users with earlier version of Office Word, Excel and PowerPoint.

To solve the compatibility issues of new XML based Office files between various version of Office 2007, 2003 and 2002 (XP), Microsoft has released Microsoft Office Compatibility Pack, which when installed on the computers of users using Microsoft Office 2003 or Office XP (2002), will allow them to open, edit and save documents in the new 2007 XML formats.

Another solution to allow a file created by Office 2007 to instantly available and readable or editable across all editions of Office suites, especially Office for Mac which also does not support new XML formats, is to save the file in an earlier Office format (97-2003) manually. To do so, a user will need to manually select “File Save As” option (cannot just simply click on Save button, which will still save as new XML format), and then select the file type and format as “Word/Excel/PowerPoint 97-2003 Document” (.doc, .xls, .ppt) format in the dialog box prompted.

Above methods are either troublesome, easily forget to perform or complicated to be implemented, as likely most user will be using old Office suites rather than upgrade to the new Office 2007. So installation of Office 2007 compatibility pack will be an massive exercise if you’re a system administrator managing thousands of clients. In this case, it would be easier to force the Office 2007 to save files in Office 97-2003 format, especially when you want to maintain a standard format for Office documents while company slowly migrate and convert to Office 2007. To save a file as old Office format automatically whenever click on “Save” in Office 2007, you can set or change the default file save options including file format or extension by using Group Policy (GPO).

To enable managing of file save options via GPO, firstly download 2007 Office System Administrative Templates (ADM), and then add the Microsoft Office 2007 Administrative Templates to the Group Policy Management Console. In the left pane of the Group Policy Management Console, double-click User Configuration, and then double-click Administrative Templates (Classic Administrative Templates (ADM) in Windows Vista).
