Outlook reply to address is wrong

[JosdeWit]

Describe the problem/error/question

I created an AI agent to send emails from my outlook account. The email is sent correctly, with the correct reply-to email address but when the receiver sends an email back, it sends an email to both the reply to address as to the sender.

Many email clients (e.g., Outlook, Gmail) treat Reply-To differently when responding.

If the recipient clicks Reply, the response should go only to the Reply-To address.

But if they click Reply All, the response may be sent to both the Reply-To and the original sender (which seems to be happening here).

If my reply answers your question, please remember to mark it as a solution.

It didn’t solve the issue, but I’ve recreated my workflow & set up my credentials again and the problem is now solved. thanks for the feedback!
