-## Roadmap
-
-App-only authentication is currently supported for the legacy remote PowerShell cmdlets that you access by using the **Connect-ExchangeOnline** cmdlet in the EXO V2 module. It doesn't work with the 9 new EXO V2 cmdlets in the module (for example, Get-EXOMailbox), nor does it work with Office 365 Security & Compliance Center PowerShell cmdlets that you access by using the **ConnectIPPSSession** cmdlet.
-
-The following list describes other items that we're working on:
-
-- Support for passing the certificate as a byte array.
-- Support for more built-in RBAC roles (Exchange Service Admin, Global Reader, Recipient Admin)
-- Custom RBAC and mailbox scoping using Azure AD administrative units.
-- Delegation support in app-only scenarios
