That box is only used to Set or Clear "Read-Only" on the files
contained in the folder, the "greyed check" you see means nothing
related to the folder itself. If you are having trouble with read only
when you open the files, you may have a permissions issue with the
folder. You say "team" of people, I would suggest you check or have the
system admin. set the permissions to said folder to READ/WRITE for the
necessary people.

Hi,
For some reason I can't remove the "read only" from one of my Excel folders.
I go into the Properties and remove the check in "read only" but when I go
back, the "read only" box is still checked. Am I doing something wrong? The
folder has to be accessible to a team of people who have to be able to make
changes, so the "read only" is really messing things up.

Thanks,
Marta
