Office 365 Groups and SharePoint Online Sharing

[Bryan Hughes]

I have yet to find a definitive answer on this in any MSFT documentation.  If I turn of external Sharing at the Root level of SharePoint Online, will this affect sharing documents to external guests in Office 365 Groups?

The client wants to turn off External Sharing in SharePoint  Online, but still have ability for external guest access and sharing in Office 365 groups and Teams.
