We recently were reviewing Office 2003 compatibility with Project Professional 2007 with a client and wanted to make a quick helpul post.
Project Professional 2007:
- OS: Microsoft Windows XP with Service Pack (SP) 2 or later
- Reporting: Microsoft Office Outlook 2003 SP2 or later required (if using the Import Outlook Tasks feature) and Microsoft Office Excel 2003 SP2 or later to use the Excel features of Visual Reporting in Project Professional 2007. Visio Professional 2007 is needed for Visio features of Visual Reporting.
- Browser: Internet Explorer 6.0 or later

Hope this helps.
