I've spent hours trying to change the permission level from the default Edit to a new permission level I added but the option is greyed out. I am the site owner
If it's not possible to edit these permissions, what's the best way to proceed? I need to be able to set a custom permission level for all Sharpoint Site documents.
Would it be best to Create Group, add the members to it and set the custom permission level. Then remove the members from the default Group?
Thanks
