Document share with external users from SharePoint 2019 on premise

Question

I have SharePoint 2019 On premise. Any ways can I share my documents from one drive to external users?

My aim is to share my Document from SharePoint 2019 on premise to specific external users only for him without anonymously sharing. Is there any way to do this without using cloud product and FBA?

Hi @Ashish Joshi ,

To enable external users sharing, you have to connect your On-Prem SharePoint environment to Azure AD Access Control. And you could configure a federated authentication between Azure Active Directory and SharePoint on-premises. The goal is to allow users to sign in on Azure Active Directory and use their identity to access the SharePoint on-premises sites.

If you have configured Office Online Server with your SharePoint 2019, here is a workaround to enable anonymous share links in SharePoint server 2019. But this workaround is not supported by Microsoft. It requires Office Online Server as the guest sharing links leverage the web-based Office viewer/editor. You could run the following PowerShell:

$farm = Get-SPFarm  
$farm.Properties.Add("GuestSharingEnabled",$true)  
$farm.Properties.Add("SPO-GuestSharingUIEnabled",$true)  
$farm.Update()
