Starting with smaller tenants (<500 seats) you cannot get a new Office 365 tenant with Skype in October! It is TeamsOnly!
Also, beginning in November some tenants (which ones – not certainity yet) with less than 500 seats will get a automatic migration offer from Microsoft. You can postpone the migration, but it is not told yet for how long. If you already have a tenant with Office 365 and SkypefBO and you have 500 or more seats: this schedule does not apply to you. Perhaps Ignite will reveal plans and schedules more. Are you ready?
