disable “sharewith” from the Ribbon and share option in sharepoint 2019

Question

I need to disable Shared With option from the ribbon and the sharing of an item for all users:

I used these two PowerShell commands but that doesn't work:

Disable-SPFeature -Identity "FollowingContent" -URL $web

and

$web.RequestAccessEmail = ""

I checked the $web.RequestAccessEnabled = false

Any idea?

Answer 1

Disabling Access Request Settings would help you to

• Disallow members to share and invite others to this site,
• Disallow access requests to unauthorized members.
• Limit some SharePoint sharing functionality for specific members.

But, it's not considered a solution to hide or disable the “Shared With” or the “Share” Menu Item for all users. Instead, you should use CSS!

• For the list, Please check How to Disable the "Shared With" and "Share" button in SharePoint?
• For the Document Library, Please check How to disable Share in SharePoint Document Library?

Answer 2

Try to use css to prohibit these two buttons from being clickable：

<style>
#Ribbon.Library.Settings.LibraryPermissions-Large,#ID_Share{
pointer-events: none;
}
</style>
