Back in April, Microsoft first announced that it will be adding Kaizala Pro capabilities to Teams over the next 12-18 months. Microsoft yesterday provided an update on this transition.  By the end of 2020, Microsoft will replace the  Kaizala service and make Teams the primary client in Office 365 and Microsoft 365 for communication with both internal employees and people in your extended networks.

Here’s the transition plan:

• The first set of Kaizala Pro capabilities will be available in Teams by the end of calendar year 2019 and includes Kaizala Actions as built-in apps in Teams, such as checklist, training, and quiz.
• By the end of calendar year 2020, additional capabilities will be added to Teams, including custom apps, flexible group types, and open directory capabilities for identity and authentication, which enables communications with anyone on Teams, whether or not they are managed in your Azure Active Directory.

Until the transition is complete, Kaizala will continue as a standalone service and Microsoft will update it regularly.
