The error "TransferConversationNotSupported" occurs because Microsoft Teams does not support handoff to live agents in Dynamics 365 Omnichannel or Copilot Studio scenarios.
This is a known limitation: live agent transfers are not currently supported in Teams channels. The handoff works via the Dynamics 365 Chat Widget (web), but not via Teams, due to platform constraints.
Workaround: Use supported channels like Web Chat, Facebook, or WhatsApp for live agent handoff, or continue interaction within Teams using bot-only experiences.
