Power Platform Community Forum Thread Details

I currently have a flow that will automatically scan my Teams channel for newly posted conversations.
Power Automate scans the conversations every 1 minute (will be bumped to 1 hour once working properly) for replies in thread.

If no reply has been made it will auto-generate a reply in thread.

The issue I currently have is that it won't stop if a reply is present or if the bot has already replied in thread.

I basically need the autoreply to run 1 time only if no reply is present and that's it.

I had "Terminate" boxes in place but got no results from them.

Please help!

Building flows

To ensure your Power Automate flow only triggers once if no reply is present and does not repeatedly send messages, follow these steps:

1️⃣ Use a Condition to Check for Replies

In your flow, before sending the auto-reply, use the "List messages in a channel" or "Get messages (V3)" action.
Filter messages where replyToId matches the thread’s ID.
Count how many messages exist in that thread.

2️⃣ Add a Condition to Stop Execution

Use the "Length()" function in a Condition action:

length(body('Get_messages')?['value'])
- If greater than 1, STOP (i.e., terminate the flow).
- If equal to 1 (only the original message exists), send auto-reply.

3️⃣ Track Whether the Bot Has Already Replied

To avoid duplicate replies, use Dataverse, SharePoint, or an Excel file to store:
- The thread ID
- A flag (true/false) indicating whether a reply was sent.
When running the flow:
- Check this storage before sending a reply.
- If already replied, exit.

4️⃣ Alternative: Use a Do Until Loop with Exit Condition

Set a "Do Until" loop:
- Check the thread for new replies.
- If a reply is found, exit.
- If X minutes pass with no reply, auto-reply.

Example Flow Logic

1️⃣ Trigger → Runs every minute/hour
2️⃣ Get Messages → Retrieves all replies
3️⃣ Condition: Check if messages > 1
🔹 Yes → Terminate
🔹 No → Check if bot has replied
4️⃣ Send Auto-reply
5️⃣ Mark Thread as Replied (Dataverse/SharePoint/Excel)
