I have the following:-
- Site collection.
- A list inside the site collection, where I have inherited the permission for the list from the site collection. Which include having the build-in groups; visitors, members, owner, excel viewer.
Now I need to include users who are visitors in the site collection to have Edit permission on the list. So which approach I should follow. I tried to stop the permission inheritance , and I modified the four groups users, but adding or removing users from the groups will affect the site collection also. As it seems that they will be using the same groups. So which approach I should follow? Thanks
