Email: Detecting Encrypted Outlook Email

Summary

Encrypted emails in Outlook help protect sensitive information by ensuring only intended recipients can read the message. There are clear indicators in Outlook and for external recipients to show when an email is encrypted.

Body


Before You Begin:

  • You must have access to your UofL email account.
  • Encryption indicators may look different for UofL and non-UofL recipients.

 


Instructions:

1.      Preview the Message in Outlook

           o   Look for a red circle with a red horizontal line to the left of the message preview. This icon indicates the email is encrypted.
