I asked this question in a wrong forum, so let me ask it again here. If
some users are given only the Read rights to excel files and some users
are given full access, if a user with RO keeps the files open, the user
with full access cannot modify the files, I think this is how it is
suppose to work, but is there any setting on the client or server I can
set to avoid locking the file, so that even if it is opened by one user,
the other user should modify the file ?
