As below you can see I create a flow, and its history status is successed. But I did not receive any messages in teams and channel.
Please help me solve this problem

Hi David,
From the screenshot you shared, the flow run status shows Succeeded, which means the flow itself executed correctly. When this happens but no message appears in Microsoft Teams, it is often related to how the Teams action is configured inside the flow.
In Power Automate, sending a message to Teams requires adding a specific action from the Microsoft Teams connector, such as:
Post message in a chat or channel
This action is responsible for delivering the message either to a channel or to a chat.
When configuring this action, there are a few important fields to check:
Post in → choose whether the message should go to a Channel or a Chat
Team → select the correct Team
Channel → select the channel where the message should appear
Message → the content you want to send
If the action is configured to post in Chat with Flow bot, the message will appear in a chat instead of the channel, which can sometimes make it look like the message was not sent.
It may also help to open one of the run history entries and expand the Teams action. In the Outputs section, Power Automate usually shows where the message was posted.
If possible, you could also share a screenshot of the flow design (especially the Teams action) so the community can better understand how the message is being sent.
Hope this helps.
