Default Sharing for SharePoint Team Sites

Create an Office 365 Group.  Do a Get-SPOSite on your group and take note of the SharingCapability.

Check this link for O365 Groups - https://support.office.com/en-us/article/Turn-external-sharing-on-or-off-for-SharePoint-Online-6288296a-b6b7-4ea4-b4ed-c297bf833e30#ID0EAABAAA=Office_365_Groups

It 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. To change this setting, you can use the Set-SPOSite Windows PowerShell cmdlet.

I am asking Microsoft for the ability to change this default setting and not have to follow up with scheduled powershell scripts to modify this after creation.
