Attack Simulation Training - external tag


I am testing the Attack Simulation Training. I noticed on the phishing email I received, that the "External" tag that Outlook assigns was missing. That would be a red flag for many people. Is there a way to make this more realistic and have the External tag?

Hello JG
Yes, you can enable external email tags via Windows PowerShell by typing the following lines and pressing Enter: `Set-ExternalInOutlook -Enabled $true`. Then restart your PC and check Outlook after 24-48 hours to see if the External warning tag or label appears¹.

However, external tagging is disabled by default, so you may connect to Exchange online PowerShell and run the command `Set-ExternalInOutlook –Enabled $false`².

There are multiple ways to add [External] tag to emails received from outside the organization. You can apply [External] tag using transport rule in Exchange and Office 365. You can also set up [External] tag using rules in your third-party gateway³.

I hope this helps!
