Send email on behalf other person in Power Apps (Office365Outlook.SendEmail)

Hello everyone. I need help with this tricky question.

I have a Power Apps application and I use the Office365Outlook connector to send an email (.SendEmail) when a button is clicked.

I need this email to be sent on behalf of a service account and not on behalf of the person clicking the button.

Things to keep in mind:

I need to do this in Power App. I am aware that it can be done seamlessly with Power Automate.
The application is used by the entire company so sharing the mailbox with everyone is not an option.

Is there any trick I can do, via connections or similar, to achieve my goal? Also, If what I want to do is not possible at all and the only option I have left is to use Power Automate, I'd appreciate a confirmation.

Thanks in advance

Something like this should work for you

Add the service account as a user to the Dynamics platform, enable the mailbox of this service account.
From your power app instead of sending email directly, do this
Create an email record in the Dynamics system, set the From field to the service account
Set the subject, body etc to whatever is needed
Save the email record, it should save as draft.
Use the "SendEmail" action to send this mail either via a Power Automate/Workflow or directly from power app using this experimental feature

Hi @enriqueglopez
Actually this quite easy to implement.
1. Create Service Account
2. Assign License for this account and enable Send Email function on this Account
3. Create flow with on behalf of Service account.
4. Create connection with SA account. Add Appropriate action line "send an email". If you want to send email to external addresses make sure that in your organization this not restrict with DLP. If this restricted for " Send an email" action. My recommendation create SMTP connection and use SMTP action its more secure.
5. If you want send email from Share mailbox address make sure that you added Service account as member.
6. added flow to Canvas or MD app, or run based on trigger

Hope this will help.

This is not possible through Power Apps. You need to create a flow and connect the service account.

Hi

Actually this is completely doable. If the user who is clicking the button has send on behalf privileges for the Mailbox that the account owns, certainly you can set the From via the options { From: emailaccountorservice }

I do it all the time
