Question details

The user wants to know if they can remove or customize the 'External' sender tag on notification emails triggered by Power Automate workflows.

How to Remove or Change the External Tag in Power Automate Emails

Product: Microsoft Power Automate
Device & OS: not provided
Scenario: Configuring automated email notifications within a Power Automate workflow.
Observed behavior: Emails sent via the workflow display an 'External' tag in the recipient's inbox, which the user wishes to remove or modify for a cleaner appearance.

Before you start

Note that the 'External' email tag is generally a tenant-wide security feature managed in the Microsoft 365 Exchange Admin Center, not an individual setting you can simply toggle off within a specific Power Automate flow.

Solution 1Recommended

Modify Tenant-Level Exchange Settings via IT Admin

Because the External tag is a global Exchange Online setting, it must be adjusted by a Microsoft 365 administrator using PowerShell.

The 'External' tag is designed to protect users from phishing by clearly identifying emails sent from outside the organization. Power Automate emails often receive this tag if they are sent using generic connectors or external accounts. Removing it requires admin privileges to exclude specific senders or domains from this tagging.

Contact your IT Administrator

Reach out to your Microsoft 365 Exchange Administrator to discuss exempting the specific sender address used in your Power Automate workflow.

Run Exchange Online PowerShell

Administrators must connect to Exchange Online via PowerShell to adjust global external tagging behaviors.

Update the AllowList

The administrator can use the 'Set-ExternalInOutlook' cmdlet and add your specific Power Automate sender email or domain to the AllowList, effectively bypassing the External tag.

Modify Tenant-Level Exchange Settings via IT Admin

Admin Access Required: You cannot remove this tag directly from the Power Automate user interface. It strictly requires Exchange Admin Center access.

Solution 2

Consult the Microsoft Power Automate Community

If you need workflow-specific workarounds or want to check how others handle generic email connectors, the official community is the best resource.

Frequently Asked Questions

Can I disable the External tag for just one specific Power Automate flow?

No, the External tag is a tenant-wide security setting managed in Microsoft Exchange. To prevent the tag on a specific flow, your IT administrator must whitelist the exact sender address used by that flow.

Why do emails from my flow show as External even if I am an internal user?

This usually happens if your flow uses a generic 'Mail' connector or an external SMTP server instead of the standard 'Office 365 Outlook' connector bound to your internal Microsoft 365 account.

How can I change the sender name in Power Automate to make the email look more trustworthy?

Instead of using the generic Mail connector, use the 'Send an email from a shared mailbox (V2)' action in Power Automate. As long as you have permissions for that internal shared mailbox, the email will route internally and display a recognizable, trusted sender name.
