I created a flow which is triggered by receiving email on my outlook account and then sends a pre defined message on Teams. I turned on the flow. The trigger is initiated when I received a mail on my outlook account, but it doesn't send the message in teams, specifying the below reason->

Error

Action 'Post_message_in_a_chat_or_channel' failed.

Request to the Bot framework failed with error: '{"error":{"code":"BotDisabledByAdmin","message":"The tenant admin disabled this bot"}}'.

On Expanding "Post message in a chat or channel" :

Please help me resolve this.

Thanks & regards

Thanks for sharing the error details. Based on the message:

Error: "code":"BotDisabledByAdmin","message":"The tenant admin disabled this bot"

This issue occurs because your Microsoft Teams admin has disabled the Flow bot (Power Automate bot) in your tenant. This bot is required to post messages using the "Post message in a chat or channel" action in Power Automate.

✅ How to fix it

You (or your IT admin) will need to enable the bot in the Teams admin center:

Go to: Microsoft Teams admin center

Navigate to Teams apps > Manage apps

Search for "Power Automate" or "Flow bot"

Check the status — if it says Blocked, change it to Allowed

Also, under Permission policies, ensure the bot is not blocked by policy

If you're not a Teams admin, share this info with your IT department to get the necessary access restored.

⚠️ Important: If the admin decides not to allow the bot, there’s unfortunately not much that can be done. Posting messages to Teams via Power Automate requires this bot, and no direct workaround exists without it.

🔁 After it's enabled

Once the bot is enabled, try re-running the flow. It should be able to post messages to Teams without error.

Let me know if you'd like a version of the flow using alternatives (like adaptive cards, webhooks, or email) in the meantime.

Hello, @Lagortinez my team is still having similar issues. I tried following those steps and I looked in Teams admin center and the closest app I could find was: "Power Automate Actions".

It is set to unblocked and assigned for now to the 2 accounts we are trying to the test with. Still getting the error.

I am confirming that they are not trying to post to a private channel and that they are both members of the channel. Still getting this error:

Any other suggestions?
