Microsoft Teams: your own bot (not offered)

Setting up your own Azure Bot for Teams is no longer offered — neither on your PC (a Cloudflare tunnel, your router or a company relay) nor on your organisation server. Use the SphereHarness Teams app instead: your Teams admin adds it once, you switch it on in the desktop agent, and there is nothing to register in Azure. Microsoft Teams: the SphereHarness app.

If you set up your own bot with an earlier desktop agent: switch to the SphereHarness Teams app, then delete the Azure Bot and its app registration in your Microsoft tenant if nothing else uses them. WhatsApp and Telegram are unchanged: Channels & Messaging.
