On March 4, Microsoft is making a change intended to improve security when sending emails via Outlook mobile.

For those who use Outlook mobile on iOS and Android, Outlook will clearly alert you when an external recipient — in our case, someone outside the University — is in the email address list when composing or replying to email messages.

When you are composing or replying to a message with external recipients using Outlook for iOS or Android, the external recipient email address is highlighted in the address list as well as in the body of the message if @mentioned. A small notice will be visible in the message header during the “compose” or “reply” process and is not visible by external recipients once sent.

Microsoft intends the external recipient notice to improve security and help prevent sensitive information from being inadvertently emailed outside your organization.

The notice will only appear if you are using Outlook mobile on iOS and Android.
