Using shared mailbox in the Power Automate flow
The instructions below explain how to use a shared mailbox in a Power Automate flow for email notifications, enabling customization of the "From" field in production environments. First, create the shared mailbox in the Microsoft 365 Admin Center, then update the 'Send email' action in your flow to use it as the sender.
Step 1) Set up a new shared mailbox in the Microsoft 365 Admin Center.
Watch the video below for a step-by-step guide on creating a new shared mailbox in the Microsoft 365 Admin Center (click the 'play' icon to start watching).
Notices:
1. After creating the shared mailbox, make sure to assign "Send As" permission to the account that runs the Power Automate flow.
2. In the example shown, we created a shared mailbox with the general name "No Reply" (which appears in the From field). However, you can use your app name or any other preferred name instead.
3. No separate license is required (your shared mailbox can store up to 50GB of data without you assigning a license to it).
Step 2) Update 'Send email component' in the Power Automate flow.
