- Needs the correct syntax and workflow adjustments to successfully parse dynamic user details into functional Yammer mentions.

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.
Open your Power Automate flow and locate or add the action that retrieves user details (such as 'Get user profile' or 'Get user details').
Add a 'Post a message' Yammer action to your flow where you want the notification to occur.
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']}.
Save your flow and run a test to ensure the user is correctly mentioned and notified in the Yammer group.
Resolve Publishing-Context Errors
If your flow fails to save or run due to a publishing-context error, reverting to the classic designer can resolve the issue.
