Flow - sending emails from a service account

Hi - i've got an approval flow for announcements that are added to a Sharepoint list.

I need the announcement when approved to be emailed out to the whole organisation from a service account ("Important Announcements") with a donotreply email address.    I understand that right now every email will go out from me as owner of the flow which is unacceptable.


Which is the best way to do achieve this?


1)  Do I switch back to SP 2013 workflow to send out the email  (as it was very easy to do in Sharepoint designer).  Can SP workflow pick up a modify event once the Microsoft Flow has updated the approval status on my item,or is running flow alongside SP workflow a bad idea?


2)  Would the "send from Shared mailbox" within Flow allow me to do this.   I'm confused about permissions if this is the solution - do I need to build the flow whilst logged in as the service account for this to work?   Or can I just add a service account as an owner for my flow?    

Are there any other issues that I'll run into when trying to send emails from a service account?

Many thanks

Hi @IanROH


Do you want to send an email to the whole organization account of a service?

For your first idea, do you use “Alert me when items change” feature in SharePoint designer? I think it is not necessary to send email via SharePoint workflow alongside running Microsoft Flow.


For your second idea, if you use “Send an email from a shared mailbox” action within your flow, your account should have permission to access the mailbox.


Besides, you could configure your flow as below:7.JPG

Within From (Send as) field, you could fill your service account, but the field requires "Send as" or "Send on behalf of" permission for that mailbox.
