Currently, Power Automate does not provide a built-in action to use the @Everyone feature in Microsoft Teams group chats.
If you want to automatically notify individual all members of a chat, you need to use the Microsoft Graph API and include proper mentions in the message payload.
This guide shows how to create messages that mention @everyone in a Teams chat using Power Automate.
Step 1: Extract Teams Group Chat ID
- Open the Microsoft Graph Explorer: https://developer.microsoft.com/en-us/graph/graph-explorer
- In the Query Input Box, paste this: https://graph.microsoft.com/v1.0/me/chats
- Click Run Query
- Under Response pre view, find this:
- Copy it to Notepad (this will be used in the flow).
19:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@thread.v2
Step 2: Power Automate Flow
Actions
- Trigger:
- Manually trigger a flow (or any trigger you want).
- Initialize Variable:
- Name: GroupId
- Type: String
- Value:
<paste your chat ID>
- Send a Microsoft Graph HTTP request:
- URI:
https://graph.microsoft.com/v1.0/me/chats/@{variables('GroupId')}/messages - Method:
POST - Body:
- URI:
{
"importance": "high",
"body": {
"contentType": "html",
"content": "Hi <at id=\"0\">Everyone</at>"
},
"mentions": [
{
"id": 0,
"mentionText": "Everyone",
"mentioned": {
"conversation": {
"id": "@{variables('GroupId')}"
},
"displayName": "Everyone"
}
}
]
}
- Content-type:
application/json
Using Microsoft Graph in Power Automate is currently the only way to programmatically mention @Everyone in a Teams group chat. By following the steps above, you can ensure that your message properly notifies everyone without errors, keeping your team informed efficiently. This approach is reliable, lightweight, and works directly with the chat’s conversation ID, giving you full control over mentions in automated workflows.
