Nightrider,
will my files and the Outlook data be lost.....
Have a dig around
Code:
C:\Documents and Settings\<username>\Local Settings\Application Data\Microsoft\Outlook
or
Code:
C:\Users\<username>\AppData\Local\Microsoft\Outlook
depending on your version of windows.
Whether your data files will be usable is another matter, but that's where they can generally be found, and Office/Outlook uninstall shouldn't touch them.
