If you're using the Flow bot, it cannot post to private or shared channels unless explicitly added.

Hi,

Option 1: Check Flow Owner Permissions

Ensure the flow owner is a member of the Teams chat/channel

The person who created the flow must be added to the Teams chat

If you're not the original creator, ask them to add you to the chat or transfer flow ownership

Option 2: Use Service Account/Bot

Instead of personal account, use a service account:

Create a dedicated service account for automation

Add this service account to the Teams chat

Configure the flow to use this service account's credentials

Option 3: Change Connection Authorization

Go to your Power Automate flow

Click on the Teams connector action (Post message, etc.)

Click "Change connection"

Select "Add new connection"

Sign in with an account that IS a member of the Teams chat

Save and test the flow

Option 4: Use Different Teams Action

Switch to a different Teams action that has broader permissions:

Instead of: "Post message in a chat or channel"
Use: "Post message as the Flow bot to a channel"

This method posts as the Flow bot and typically has fewer permission restrictions.

Option 5: Configure Flow Bot Permissions

Go to Microsoft Teams admin center

Navigate to Teams apps → App permissions

Ensure Power Automate app has necessary permissions

Add the Flow bot to your Teams chat manually

Option 6: Use Graph API Connection

For more control, use Microsoft Graph API:

Use "HTTP with Azure AD" connector

Configure Graph API permissions for Teams

Use appropriate API endpoints for posting messages
