I'm currently building document libraries for my team and am running into a privacy issue. I have created the library, broken permission inheritance, and added only the single group that needs access. However, everyone on my team (outside of that group) is still able to access the library and documents. I'm assuming that this is due to Limited Access permissions, but I cannot figure out how to resolve this. I did try to go into the Limited Access list and remove a specific user, but he is still able to view the material.
For some reason I'm unable to wrap my mind around this and would greatly appreciate any and all help I can get.
Updates:
I am currently operating on SharePoint 2013 (not 365). Also, there are other libraries contained within this SharePoint site. Essentially, there is 1 main site, and 5 document libraries. Each document library is specific to a location and within each folder that's created, unique project members will be added to that folder...which I believe is creating the 'Limited Access'. However, I need to create a document library, break inheritance, and only allow a small # of people into the library due to very confidential information.
