Regarding Actionable Email Developer Dashboard --> Sender email address from which actionable emails will originate

Question

Hi Team,

I'm testing Actionable cards in Outlook with the Actionable Email Developer Dashboard,

For this, I created a new provider with sender E-mail id as

it-@.onmicrosoft.com

The card is working fine when I sent a mail from it-@.onmicrosoft.com

But the problem is the card is still loading even though I am sending a mail from
hr-@.onmicrosoft.com

Note: If I send a mail from a different E-mail for example [e-mail] the card is not loading


How to debug this issue further
