# Marking External E-mails

Outlook can mark emails from external sources with a note to make it easier to recognise spam and phishing threats.

It will look like this:

- **Outlook for Windows**

However, please do not rely completely on this labelling. For one thing, the technology can also make mistakes and it is always possible to take over a colleague's account.
