Groups Guest access and SharePoint access
"By default, all SharePoint site collections that are part of an Office 365 Group have the sharing setting set to Allow sharing only with the external users that already exist in your organization’s directory. To change this setting, you can use the Set-SPOSite Windows PowerShell cmdlet." from https://support.office.com/en-us/article/Manage-external-sharing-for-your-SharePoint-Online-environment-c8a462eb-0723-4b0b-8d0a-70feafe4be85?ui=en-US&rs=en-US&ad=US
Hence, to share with unauthenticated users, it is enough to change the default by powershell.
I am still having issues (and lots of support tickets) as Guest members of a new Group cannot access the Groups SharePoint files. Referring to 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&fromAR=1#ID0EAABAAA=Office_365_Groups
The article says: By default, all SharePoint site collections that are part of an Office 365 Group have the sharing setting set to Allow sharing only with the external users that already exist in your organization’s directory.

Q: If I change the Tenant (global) settings, do I still have to change the settings for the site collections related to the Office 365 Groups with the SPO cmdlet?
NB: I ask this as I do not see an obvious Site Collection in the lhttps://iasahome-admin.sharepoint.com/_layouts/15/online/SiteCollections.aspx that is related to my Office 365 Groups (for example storage used is zero when there are many files in the Group site) - related, where do I see the storage used for the SharePoint files associated with a group?
- Didn't hear back so I Set-SPOSite -Identity https://xxx/sites/yyy -SharingCapability ExternalUserAndGuestSharing The SP article on this https://support.office.com/en-us/article/Manage-external-sharing-for-your-SharePoint-Online-environment-C8A462EB-0723-4B0B-8D0A-70FEAFE4BE85 is not clear which capability maps to which value to use and has no date so who knows if it is in sync with Groups :-(
