Aside: having a space at the beginning and/or end of the filename has
no good effect and may cause problems, so don't do it.

It's always a good idea *before* you write an os.system call on *any*
operating system to try a few sample commands at the command line. You
would find in this case that the problem exists there too -- it has
nothing to do with Python. The problem is that the first argument
*contains* spaces, but the Windows command processor splits the command
line on spaces, so it thinks the first argument is  'C:\\Documents'. On
both the command line and in your script, you will need to wrap quotes
around each argument that does/could contain spaces.

[untested]
os.system ('xcopy /s "%s" "%s"' % (filepath, backup))

Hint: you should find it easier using raw strings for Windows
filenames:
    backup = r'D:\temp\outlook'

HTH,
John
