Impact of deactivating the Limited-access user permission lockdown mode feature

Question

Hello,

I have a SharePoint 2016 farm. I have an internal site and external site. I have a requirement to provide granular level permissions to individual folders in a document library. I attempt to do this by clicking the Share function on the folder but get a message that I cannot because of the Limited-access user permission lockdown mode feature. What is this feature used for? Are there features that are dependent on this feature? What is the impact of disabling it?

Hi @MDuBose ,

As this official article mentioned:

And the sharepoint server publishing infrastructure feature requires the limited-access user permission lockdown mode feature to work correctly. so if you disable the feature, the sharepoint server publishing infrastructure feature mayn’t work in some ways.

Unless you don’t use the sharepoint server publishing infrastructure feature, you can share a folder with other users and other users can enter the folder normally. if you enable the sharepoint server publishing infrastructure feature, the limited-access user permission lockdown mode feature will be enabled accordingly. The users who you shared the folder with will be granted the limited-access permission and become unable to enter the folder and get the error messages below. So if you activated the sharepoint server publishing infrastructure feature, there are two options for you to move forward:

1. if you want to use the sharepoint server publishing infrastructure feature, you will lose the feature of sharing a folder. you can share files in the folder with other users instead.
2. if you don’t use the sharepoint server publishing infrastructure feature, you can disable the limited-access user permission lockdown mode feature to restore the feature of sharing a folder.
