Groups Guest access and SharePoint access
Hi David-
We are also experiencing this issue and running SPOSite is not working as suggested in prior posts. Unless the user is already registered in Azure AD there is no way to share a file or folder from an Office 365 Group Team Site without receiving that dreaded message. Our requirements are similar to most, where Group Owners want to only share select Folders/Files with external users with having to add to the external user to the Office 365 Group.
I am hoping this much needed feature is coming soon.
Best,
Bobby
HI Bobby Cruz.
As already said in this thread and in several other threads, in order to share Group files and folders with external users not members of the Group itself, two conditions should be met:
- External sharing should be enabled at tenant level in Admin Center
- External sharing should be enabled at Group level by PowerShell
Follow carefully, step by step, the various sections in this article: https://support.office.com/en-us/article/Turn-external-sharing-on-or-off-for-SharePoint-Online-6288296a-b6b7-4ea4-b4ed-c297bf833e30?ui=en-US&rs=en-US&ad=US#ID0EAABAAA=Office_365_Groups
If it doesn't work, then double-check your steps: it MUST work if everything is well done.
Good luck.
- Just went through this nightmare again - thanks Bobby for actually including the PS needed.
I know you have probably answered this a 100 times, but I still have to ask.
- If you turn off Sharing to external users in the SPO Admin Center, will this block sharing with guests in Office 365 Groups Site Collections?
- If you turn of External Sharing on the root SPO site, will this block sharing with guests in Office 365 Groups site collections?
This is the scenario a client wants to turn off sharing outside of the organization on the root site, and allow external sharing, for Office 365 Groups Site Collections. Is this even possible?
- Yes. The sharing setting in individual site collections cannot be less restrictive than global setting in SPO Admin Center. So, if you switch off sharing at the global level it will not be allowed for the individual site collections (including those connected to Groups).
- No. The sharing setting of every site collection (including the root site collection and those connected to Groups) is individual.
So what you want is feasible: enable globally sharing with external users in the Admin Center, disable it for the root site collection and enable it (by PowerShell) for individual Groups.
Hope it helps...
Salvatore Biscari Thank you very much.
I had already tried it with a test group and root site after I posted the question and it worked, but it is nice to see confirmation, from an expert.
The MSFT documentation on SPO Sharing and Office 365 sharing is confusing and circuitous.
Hi Salvatore,
Well I am happy to say that I figured out how to get External Sharing for Guests working for my groups Office 365 Team Site.
Scenario-
Unable to Share a Group Folder or File with External Users (Guest)
Guest Sharing Enabled at the Tenant Level - Yes
Executing Set-SPOSite -SharingCapability ExternalUserAndGuestSharing - Did not work, message still indicated I needed to EnableGuestSharing at the Tenant Level (Although it already was).
What worked for me was executing the following command from PS to enable guest sharing.
set-spotenant -SharingCapability ExternalUserAndGuestSharing
then running this against the site I want to enable guest sharing
set-sposite https://site.sharepoint.com/teams/development -SharingCapability ExternalUserAndGuestSharing
Long story short, although guest sharing was enabled in the Admin Center, for whatever reason, PS still saw this setting as "off". By enabling this setting using SET-SPOTenant worked.
Happy to know that you solved the issue!
Regards.
Thanks Salvatore!
So am I!!!
Hi Salvatore,
Yes, I am aware of the two conditions and although I have confirmed it does not seem to work
I will give it a go again and see if the outcome is different.

BobbyVery strange!
It looks like a bug: have you tried to open a ticket with support?
Hi Salvatore,
I am going to try again today. I haven't reach the point of frustration just yet, but if the outcome turns out to be the same I will likely open a ticket with support to take a look.
Best,
Bobby
