We’re planning on updating the default sharing setting for Office 365 Group connected SharePoint Online site collections.
How does this affect me?
Currently, the default sharing setting for these site collections is set to allow sharing with external users that are already in your organization’s directory. Based on your feedback, we’re planning to update this default to allow sharing with authenticated external users only if your tenant allows for Office 365 Groups to have guest members. If your tenant disallows guest members in Office 365 Groups, there will be no change to your the external sharing setting default.
With this change, all new group site collections will be created with the new default setting for external sharing only if your tenant allows for Office 365 Groups to have guest members. Existing group connected site collections will not change at all. Only new group site collections created in your tenancy will have the new default setting.
We’ll be gradually rolling this out in August, and the rollout will be completed in the next few months.
