Additional document library shielded from guests?
Hi, we're soon moving from classic sites to M365 group connected and Teams site collections. In classic we had set up the logic that internal users had a document library with unique permissions that only they could see. Tenant external users / guests were excluded. This worked because we could invite guests into the "Site Visitors" group and have internal users live in "Site Owners" and "Site Members". We then gave the "internal" document library unique permissions in that we removed the "Site Visitors" security group. This made it so that external users / guests could not participate in that library. Now, moving on to the M365 group security model. Here, the SharePoint security group "Site Visitors" is not used. M365 group owners are put into the security group "Site Owners" and M365 group members go into "Site Members". This effectively mixes internal members and guests allowing them access edit permissions wherever "Site Members" is set. I can't come up with a mechanism that would allow me to have a secure document library with this model since a third security group is not used like "Site Visitors" used to be. Looking forward to your input, perhaps you have an easy solution for this. Thanks. The SharePoint security group "Members" nowSolved1.5KViews0likes3Comments
