我可以在 Teams #Bot 框架中刷新聊天历史记录吗

Question

Is there any way to refresh/clear BOT chat history and start new conversation in MS Teams. If Yes please let me know how to do it.

Answer 1

There is (as of the posting of this answer) no way to delete teams chat history, so there is no way to clear the previous messages of a bot from the teams client. There are ways to clear a bot's conversation state, but as the bot's Microsoft app ID is tied to a Teams app ID as soon as you add the channel, the messages displayed on the teams chat window are there to stay no matter how you handle your bot's state/history storage.

The only work around for this is to remove the bot from Teams entirely, and redeploy it using a new Bot Channels Registration/Web App bot, which doesn't, per se, delete the history so much as create a totally new bot.
