In this blog, let’s discuss implementing an ‘external’ tag identifier on your business email. This feature implements an “External” tag identifier on Outlook for email messages received from outside your organization. Microsoft created this feature in hopes that the external tag will help users easily identify spam and phishing threats from external senders. When someone outside your organization receives an email, an “External” title will be present in Outlook on the web, Outlook for Mac, Outlook for iOS, and Android. After clicking the external tag, the email address for the sender will be shown.
