Given that documents stored in an Office 365 Group "Files" doc lib would appear to be located in a /sites site collection I wonder is it safe to assume that the upcoming Team Site enabled 365 Groups will be located there ? I'm trying to figure out if I should bother creating Team Sites currently for a new deployment given this impending change and wait to see how 365 Groups & Team Sites will be aligned.

This was answered on Yammer, but yes, the group sites do, and will continue to exist in the /sites/ path.

Hi -
Can you please roll it out to me? I am on the Office 365 Business Essentials. Thanks!

  It doesn't work on that way...you cannot ask for a custom rollout of an Office 365 feature

    How about a rollout to all Office 365 Business Essential users/lisences?

  Can one specify a different location based on the type of group e.g. clients and suppliers? We want to keep all client geoups in sites\clients\[group] ando supplier groups in sites\suppliers\[group]. It would also make sense to split actual clients from prospective clients.

    So no, all groups go under the sites path, just like everything else in SharePoint Online.
