Sending email from "Created By" email

Create flow using "Send as" by person’s name in "Created By":


I have a flow that simply sends out an email to all users in my organization.

Users can choose from 5 types of emails which are formated in HTML through advanced settings. Therefore, the flow branches into 5 choices and a different email is sent depending on what they choose. (IT Alert, General Alert, etc...) 


The emails kicks off but it always shows it is coming from me and I want it to show it is coming from the originator of the email or created by, not me.


If I add anyone to the “Send As” field under advanced settings it fails. The fail message I get indicates, “You are not authorized to send mail on behalf of the specified sending account..." which is fine, I get that the users cannot send mail as if they are me, but they should be able to send the notifications out if they are them.


MS Flow kicks off emails from the person that created the workflow. 


REQUEST: I would like to see MS FLow to kick off based on a value of a field, preferrably "Created By" not contingent on Active Directory settings.


Thank you.

Hi @RoccoCastellano,


If you want to use From (send as) field, the email address that you fill in must have “Send as” or “Send on behalf of” permission for that mailbox.

More details about how to allow someone else to manager your mail, please check the following document:
Allow someone else to manage your mail and calendar


Kicking off Microsoft Flow based on a value of a field is not supported in Microsoft Flow currently, if you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:

Thanks Kris.


yes I was aware of the information regarding the "send As" permissions for that field. I have put in an idea at that site you detailed above. 


Thank you again for reinforcing that... it is appreciated. 


Have a great day.
