One-Click Unsubscribe option is not working

Posted on by 134
Dear Team,
One-Click Unsubscribe feature switch has been enabled in our environment. But still the email that was sent using Outbound marketing doesn't show this Unsubscribe option in the header of the email. Have checked in Gmail and as well as in Yahoo. 
Do I have to do anything else apart from enabling the Feature switch. Is it possible to manually configure the header?
We have quite a few commercial emails waiting to be sent and now its put on hold until this issue is resolved. Let me know if anyone faced this issue and how to resolve it?

    Apparently the Subscription center does not work via the "Test send" option...Anyone else experiencing this?

    According to the Microsoft documentation.
    One-click unsubscribe support for emails - Dynamics 365 Customer Insights | Microsoft Learn

    Gmail considers several factors before surfacing the one-click unsubscribe link in the email client, even when the one-click unsubscribe headers are present in the email. Here's a community thread from Google where this has been discussed: List-Unsubscribe header not providing the option to unsubscribe.

    If you've turned on the feature switch, all the future emails sent from the system includes the one-click unsubscribe headers. As long as the email contains the headers as per the specification, you can be rest assured that you're complying with Google’s guidelines. To verify this, you can download the message or select “Show Original” in the menu item of the message to verify that the headers are present.
