Ensure email from external senders is identified
Why This Matters
Emails from external senders are a primary vector for phishing and social engineering attacks. Without clear identification, users may inadvertently trust malicious messages sent from outside your organization. Enabling the external sender tag provides a persistent visual cue that helps users exercise caution before interacting with unknown senders, reducing the risk of successful phishing attempts. This feature also supports security awareness training by giving users a simple, consistent indicator of email origin.
What Aether365 Checks
Aether365 verifies whether the ExternalInOutlook setting is enabled, which adds a visible "External" tag to emails from senders outside your organization. This check appears in your Aether365 dashboard under the microsoft-365 checks section.
