Get Email Subject Bad Request

Posted on by LR-29120802-0

I am attempting to create a flow that takes the subject of an email and populates it in an excel worksheet. I need help getting the Get Email Subject to work in my flow. I am not sure why its not working, see screenshots below.

What happened:
The flow tried to get an email's subject, but the information it used to find the email wasn't in the right format, so it couldn't continue.

How to fix it: 1.Go to Edit mode in your flow. 2.Find the "Get Email Subject" action. 3.Check the "messageId" field. Make sure it uses the correct dynamic content (like "Message Id" from the trigger) instead of the email subject. 4.Save and test your flow.

Hi @LR-29120802-0,

In the Get Email Subject action -> Message Id you have placed Subject which is wrong, Click the dynamic content and choose in When a new email arrives in a shared mailbox (V2)-> Message Id if you are not able to see that you have click "see more" and then scroll down you will find that

(If this answers your question you can mark as Answered and give it a Like, it helps others to find the answers)

Hi @LR-29120802-0,

The first action already returns the subject. The second action should not be needed to retrieve the subject.

See an example below in a Compose action. You should be able to use that Subject dynamic content field directly use that in your Excel action.

Happy to help out 😁
