292533 How to use Windows Program Compatibility mode in Windows XP
This issue may occur on a computer that is running Windows XP if the Outlook.exe file was configured to open by using the Windows Program Compatibility mode setting. When you set compatibility for Outlook to Windows 95 or to Windows 98/Windows Millennium Edition, Outlook displays this error message. This occurs because the location of the Outlook Profile information in the registry is different on a Windows XP-based computer than it is on a computer that is running Windows 95, Windows 98, or Windows Millennium Edition.
