Where can I find help for converting my Microsoft Office files to the new Office 2007 open XML format?
A. Microsoft has made available the Microsoft Office Migration Planning Manager, which you can download here. It consists of several utilities that use Microsoft Office Access 2007 to run reports on the entire network and gather information on legacy Office documents. Then using the Office File Converter, you can convert these legacy documents in bulk to Office 2007 file versions.
