Guest User added team should not be allowed to search internal contact and start chatting with them?
first I recently added some guest users to active directory and added them to our team as member. it was nightmare as they can search any our domain user in contacts and start chatting with them. secondly, we tried to share sharepoint library folder to external user, and they become team members. it become nightmare for me to share dozen of large files with our external clients. how i should overcome this issue?
