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 
 
 Outlook on the Web 
 
 Android 
 
 
 
 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. 
 If you would like this labelling, please contact us.
