Replace SharePoint Designer Workflow with Power Automate

Because SharePoint Designer 2013 does not support custom sender addresses, migrating your workflow to Microsoft Power Automate is the most effective solution.

Microsoft Power Automate has replaced SharePoint Designer for workflow automation. Using the Office 365 Outlook connector in Power Automate allows you to specify exactly which email address appears in the 'From' line, provided proper mailbox permissions are in place.

1
Open Power Automate

Log into your Microsoft 365 account, click the App Launcher (waffle icon) in the top left corner, and select 'Power Automate'.

2
Create or Edit a Flow

Navigate to 'My flows'. You can either edit an existing flow created for your SharePoint list or select 'New flow' to create an automated cloud flow triggered by a SharePoint event (e.g., 'When an item is created').

3
Add the Email Action

Click 'New step' and search for 'Send an email'. Select the 'Send an email (V2)' action under the Office 365 Outlook connector.

4
Configure the 'From' Address

In the Send an email (V2) card, click on 'Show advanced options'. Scroll down to the 'From (Send as)' field and enter the email address you want the email to be sent from.

5
Save and Test

Save your flow and run a test to ensure the email is successfully delivered displaying the newly configured sender address.

Exchange Permissions Required: If you receive an error stating you do not have permission to send from the specified address, an Exchange Administrator must grant your account 'Send As' permissions for that specific mailbox.

Frequently Asked Questions

Why can't I change the sender address in SharePoint Designer 2013?

SharePoint Designer 2013 is a legacy tool that hardcodes the sender address to the default SharePoint system address for online environments. Microsoft has deprecated this software and has not updated it to support modern Exchange integrations.

Can I use a shared mailbox to send emails via Power Automate?

Yes. Power Automate offers a specific action called 'Send an email from a shared mailbox'. You just need to ensure your user account has been granted explicit permissions to access and send from that shared mailbox.

Are SharePoint 2013 workflows still supported in Microsoft 365?

No. Microsoft has officially retired SharePoint 2013 workflows in SharePoint Online. Organizations are strongly advised to migrate all automated processes to Microsoft Power Automate.
