Groups Guest access and SharePoint access

Steel Contributor

Looking to confirm my understanding.  If you add a guest to an O365 from OWA, they will only have access to the associated SharePoint site if external sharing for that site has been turned on (or if external sharing was turned on a the tenant level)?  Since sites created off of groups don't show up in the SharePoint Admin center, you'd have to run PowerShell to enable external sharing on that site?  Is there any other way to grant external member access to a Groups SharePoint site besides PowerShell?

Just went through this nightmare again - thanks Bobby for actually including the PS needed.

Yes, it appears to me that you need to follow more than one of the sets of instructions on this page

so this line is wrong: Choose one of the tabs below to configure sharing in SharePoint Online.
