You can change the default using PowerShell.

"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."

Santhosh,

You're right and the error message in SP is more than missleading - wrong! Having that in mind, it's even more than weired:

The 365 group dialog let you add external users that get invited to your AD.

You can also share content on the SP site with external users that exist in your AD. But you cannot use automated invitation+external user provisioning functionality through SharePoint?

In my opinion, it's simply wrong that the SP site is configured to 'only with existing users' if the 365 tenant allowes external invitation.

For my business case, there is a workarround that solves it, but one should be allowed to control that behavior at will.

Thanks for helping me understand "error messages" :-)
