Sending an e-mail notification through service account

[lliu_western]

Hi I created a Flow that sends out e-mail notifications.

But I need the e-mail to be sent out from the Service Account. 

I tried using the under the advance options --> From (Send As) , however, this one causes the flow to fail with error message of "You are not authorized to send mail on behalf of the specified sending account."

I have also saw a method of using Delegation Group so changing the D365 setting of that e-mail account. 

Does anyone have any simpler way, tips to achieve this goal?

To send out an Email from a Flow as another user you must have "Send As" permission to their mailbox.  So if you want to use a service account for this you need to do three things.

1) Make sure the flow is running under your security context.  Automatically triggered flows run in the context of the maker.  Manually triggered flows run based on whoever starts them. 

2) Make sure the service account has a mailbox they can send mail from

3) Make sure you have "Send As" permission to that mailbox.

Another alternative would be to make sure the service account has a mailbox and a Power Automate license and build the flow using that account.  Then the email will come from that account, again if the flow is triggered automatically.

Answering my own question here.

Background story I missed earlier. 

I have a PowerApps, and whenever a user perform certain actions, it requires the App to send out an e-mail notification to target audience. 

I tried using the outlook connectors in PowerApps, however, it will always uses the credential of the user that is using PowerApps.

I tried to build a flow to send out the e-mail notification and the start of the Flow is a trigger by PowerApps. The result of it is the same. The e-mail still sends out from the user the is using the PowerApps

I found a way around to achieve the goal of sending through a service account. I used SharePoint, "when an item is created" as the Flow trigger. 

And in PowerApps, in the case where I need PowerApps to trigger an e-mail notification to be sent out through the service account, I do a patch statement to that SharePoint list so it creates an new item that triggers the Flow.
