From property in Send an Email action not working

[RobWindsor]

I've been trying to use the From (Send As) property in the Send an Email action but it does not appear ro be working.

In the Office 365 administration portal I have one user (Andrew) configured for "Send as" and another user (Brian) configured for "Send on behalf". The tooltip for the From property indicates that both configurations should work.

I have a Flow that has an action that sends an email with Brian as the From user and another action that sends an email with Andrew as the From user.

When I run this Flow both email messages are sent with my account (Rob) as the sender. The screen capture below shows one example of the received email.

Unless I misunderstand how this functionality should work, it appears that the From property of the Send an Email action is not working correctly.

Hi @RobWindsor,

I have made a test on my side and the issue is confirmed on my side.

I would post this issue to my product team. If the issue is solved, I would reply here.

Best regards,
