Seems you have many problems there, and me here with no solutions.
But thanks for taking a shot at it anyway (although I have no idea what the results mean). This is what I got using your Terminal instructions:
I entered:
ls -ld /Library/Spotlight/Microsoft*
drwxrwxr-x 3 root admin 102 Jan 21 2009 /Library/Spotlight/Microsoft Office.mdimporterand got:
firstname-lastnames-imac:~ myname$ ls -ld /Library/Spotlight/Microsoft*
drwxrwxr-x 3 root admin 102 18 Dec 2009 /Library/Spotlight/Microsoft Entourage.mdimporter
drwxrwxr-x 3 root admin 102 21 Jan 2009 /Library/Spotlight/Microsoft Office.mdimporter
firstname-lastnames-imac:~ myname$ drwxrwxr-x 3 root admin 102 Jan 21 2009 /Library/Spotlight/Microsoft Office.mdimporter
I entered:
mdimport -Land got:
firstname-lastnames-imac:~ myname$ mdimport -L
