What are the permissions on the file AFTER "sg" has modified it.

If I were you I'd set the setgid bit on the directory after changing it to
of_a.  This will mean that all files in that directory will always (well
mostly) be in the group of_a.  This can be done with

chgrp of_a .
chmod g+s .

I'd also check the umask of each user.

Also as the file is an xls I'm guessing that you're accessing it via samba.
in which case you should read the samba docs on 
create mode and group definitions.

Yours Tony.
