Microsoft will retire the Skype for Business Online (PowerShell) Connector on February 15, 2021. Office 365 tenants need to check scripts to replace the connector with the Teams PowerShell module, which contains the necessary cmdlets to connect to the policy management endpoint. Once connected, scripts can interact with objects like Teams messaging and meeting policies.
