OneNote 2003 files are read-only files in OneNote 2007 until the files are upgraded.
When you start OneNote 2007 for the first time, you have the option to upgrade your notes. After the initial migration, OneNote 2003 files are opened as read-only in OneNote 2007. Use the InfoBar to upgrade your OneNote 2003 files to the OneNote 2007 file format. The InfoBar is the yellow status bar at the top of the page. The InfoBar displays the following message: OneNote 2007 does not support backward compatibility with OneNote 2003. Therefore, after you upgrade your OneNote 2003 notes to the OneNote 2007 file format, you can no longer open those notes in OneNote 2003.
Shared sessions and shared notebooksIf you work with shared notebooks, make sure that everyone uses the same version of OneNote before the notes are upgraded to the new file format.
