How to never open unexpected email attachments or links
Treat any unexpected file attachment or link — even from someone you know — with suspicion before you click.
Step-by-step guide
- Before opening an attachment or clicking a link:

- Does the sender's address look genuine (not spoofed)?
- Hover over the link — does the URL match what is displayed?
- If in doubt, contact the sender by phone to verify
- Report suspicious emails to your email provider or IT team
How to confirm it worked
- The setting is saved and active on your device
- You have tested it works before closing the page
