Exclude a folder doesn't work with Synchronisation Miror (update)

Hello, I want to make a "Synchronisation Miror Update" with exclude a folder, for example, for my folder source:
!!!Achat - 2008 0618 - Bridge retourné
in C:\Mes documents

I want to exclude this folder for not to update it on the destination folder. I put:
!!!Achat - 2008 0618 - Bridge retourné

in the exclude field, but that do not work, this folder is update in the destination folder. I try other solutions, to write in the exclude field:

!!!Achat - 2008 0618 - Bridge retourné
or
c:\Mes documents\!!!Achat - 2008 0618 - Bridge retourné
or
c:\\Mes documents\!!!Achat - 2008 0618 - Bridge retourné

always the same resultat. A problem with characters !é- peharps?

Can you test it ? (and sorry for my "French English"!)
