Scenario
Automating Yammer group posts and dynamically tagging users based on retrieved user data.
Observed behavior
Needs the correct syntax and workflow adjustments to successfully parse dynamic user details into functional Yammer mentions.
Before you start

Solution 1Recommended

Use the 'mailto:' Syntax in Power Automate

Utilize the user's email address combined with the mailto syntax to dynamically mention them in a Yammer post.

Power Automate supports mentioning users in Yammer by referencing their exact email addresses. Using dynamic content to fetch the email ensures the mention works automatically for different users.

1
Retrieve User Details

Open your Power Automate flow and locate or add the action that retrieves user details (such as 'Get user profile' or 'Get user details').

2
Add the Yammer Action

Add a 'Post a message' Yammer action to your flow where you want the notification to occur.

3
Format the Mention

In the message body, use the dynamic content for the user's email formatted with the mailto prefix. For example, type mailto:@{outputs('Get_user_details_1')?['body/email']}.

4
Save and Test

Save your flow and run a test to ensure the user is correctly mentioned and notified in the Yammer group.
