The External Tagging Feature in Outlook is a security function that helps users identify emails coming from external sources or domains. This feature adds the “External” label to emails received from domains that are not part of your company or organization.
Tagging Emails: When an email arrives in your inbox, the Exchange Online mail server automatically tags any emails coming from domains outside your environment with the “External” label. This label is displayed in the email client, making it easier for users to quickly identify that the message originates from an external sender or that it might be a phishing attempt, where someone is trying to exploit the organization’s domain to send emails without authorization.
Security and Protection: This feature is part of a broader strategy to enhance email security. By clearly marking external emails, it reduces the risk of errors when receiving potentially harmful messages or spam.
User Experience: When users receive a message labeled “External,” they can immediately recognize that it comes from outside their organization. This increases awareness and provides better protection against potential security threats.
This functionality helps minimize the risk of mistakes in handling email, increases security and accuracy when receiving messages, and provides better control over external communication. By tagging external emails (“External Tag”), it becomes easier and quicker to identify potentially dangerous messages.
