Actually I'm the type of person that doesn't care to keep upgrading if I don't have to. I am currently using the Outlook Express program on a Windows XP Professional OS but since there is no support for Windows XP anymore I am planning on upgrading to Windows 7 Ultimate 64Bit OS. I saw somewhere that Outlook Express doesn't work with Windows 7 so I was hoping you would of said Microsoft Outlook was better than Outlook Express. I have Microsoft Office Professional Plus 2010 so I guess I can use the Microsoft Outlook program when I finally install Windows 7 Ultimate OS unless like you said "Eduello" just install Windows Live for the Windows 7 Ultimate OS. So my question is -----> Should I use Microsoft Outlook 2010 or Windows Live for Windows 7 Ultimate?
