Dear Friends,

I am buliding the Automate flow for my daily task,
The idea is

  1. Send out the mail-merge ( send email v2 ) customized with the action "create a response" included
  2. Then "wait for response "and and email the outcome approve or not approve ( use reply email V3)

However, I can not find any method to show the message ID of ""Send an email V2" -> to configure the "Reply to email V3"

Some methods I have tried:

  1. Nothing show in " insert dynamic content"
  2. Use fx Expression as below instead but it also not showing
    ( outputs('Send_an_email_(V2)')?['body/messageId'] - outputs('Send_an_email_(V2)')?['body/MessageId']

Hope to hear a solution as help from here

Many thanks

    Hi @Mike PHAM

    Please note that our forum is a public platform, and we will modify your image to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data.

    Based on Office 365 Outlook - Connectors | Microsoft Learn, the behavior you are seeing is expected. The documentation explicitly states that"Send an email (V2) does not return message id" and that there is no way to get the Message ID when sending a message using this action. As a result, the Message Id required by Reply to email (V3) is not available in the dynamic content from Send an email (V2).

    If your flow needs to use Reply to email (V3), you will need to obtain the Message ID through another method, such as retrieving the sent message from the Sent Items folder using Get emails (V3) and then using the returned message Id in the reply action. You can refer to this discussion Solved: Get Message Id for Reply Email in Flow
