Sharing with external users in SharePoint - Microsoft Community

hello,

i trying set our charity's sharepoint account can share folders our partners. when try share tells me have "go external sharing in office 365 admin center enable it". have done this, error message still comes up. local person has had look, can't fathom either. can help?

many thanks,

hi marika,

since have turned on external sharing in tenant level, issue remains.

i assume affected site group site. following picture shows:

by default, sharepoint site collections part of an office 365 group have sharing setting set toallow sharing external users exist in organization’s directory. that's why grayed out in screenshot above.

to change setting, can use set-sposite windows powershell cmdlet. below steps:

1. connect sharepoint online powershell.

2. run

connect-sposervice -url https://contoso-admin.sharepoint.com -credential admin@contoso.onmicrosoft.com

set-sposite -identity https://contoso.sharepoint.com/sites/groupname -sharingcapability externaluserandguestsharing

(remember replace italic parts correct values.)

3. go office 365 group, refresh page.

for reference:

set-sposite

if misunderstood, can please share screenshot of site homepage.

thanks,

cherry
