Question

Hi all,
I want regular user in my organization be able to share data/grant permission for external users, what I did:

• Enable external sharing policy : New and existing guests
• Invite external users as guests

From sharepoint admin, I can grant permission for guests

From normal user with full control permission on a folder, user cannot find guest account to grant permission

Please give me some advice, thank you very much.

Answer 1

Hi @Jack Chuong ,

Please make sure you have enabled “Anyone” external sharing settings at both the organization level and the site level. If the Sharing policy for your SharePoint Online tenant or site is set to “Existing guests – Only guests already in your organization’s directory”, You must invite the external user to your Azure AD first in order to provide them access. To allow external sharing on any site, you must allow it at the organization level.

You have to enable “Anyone with the link”.

1.SharePoint admin center > Policies > Sharing

2.Site>Policies> External sharing> Edit

Hi @Jack Chuong

Try this script

Set-SPOSite -Identity https://domain.sharepoint.com/sites/testsite -ShowPeoplePickerSuggestionsForGuestUsers $true

Hi @Jack Chuong

You should enable external sharing at site level (SharePoint Online).

Answer 4

Hi @Rijwan Ansari ,
I enabled sharing both at site level & organization level
As you can see above, from sharepoint admin I can find guests when I grant permission for a folder.
But from normal user with full control permission on a folder , I cannot find guests when I grant permission for same that folder.
I also cannot find guests when I want to share link via email (whether I'm an admin or a regular user)

Hi @Jinwei Li-MSFT and @Rijwan Ansari
I have changed as below pic and it works now, regular user with full control permission can grant permission to guest
Or maybe because of powershell command ?

Set-SPOSite -Identity https://domain.sharepoint.com/sites/testsite -ShowPeoplePickerSuggestionsForGuestUsers $true  

Anyway, thank you very much.

It was "Only people in your organization"
