How to spot a phishing email

Learn the warning signs of a phishing email, how to check a suspicious message safely, and what to do with one before you click anything.

Last updated 10 November 2026

A phishing email pretends to be from someone you trust, such as a bank, a courier, a supplier or your own boss, to trick you into clicking a link, opening a file or giving away a password. Everyone gets them, and good ones fool careful people. This article shows you what to look for and what to do.

Warning signs

  • It’s unexpected, or it pressures you. “Your account will be closed today” or “Pay this invoice now” are classic tricks to make you act before you think.
  • The sender’s address looks slightly wrong. Look past the name to the address itself, for example a spelling that is one letter off, or an address from a free email service when the message claims to be from a company.
  • It asks for something sensitive. Passwords, one-time codes, card details or ID numbers. Real companies don’t ask for these by email.
  • The link isn’t where it says. On a computer, hover your mouse over the link, without clicking, and read the address that appears. On a phone, press and hold the link to preview it.
  • There’s an attachment you didn’t expect. Be extra careful with files that ask you to “enable content” or “enable macros”.
  • A generic greeting or odd wording. “Dear customer” instead of your name, or strange spelling. Don’t rely on this alone, because good phishing emails are well written.
  • Money details have changed. A supplier or colleague suddenly gives new bank details. Check by phoning them on a number you already have, never one in the email.

What to do with a suspicious email

  1. Don’t click any links or open any attachments, and don’t reply.
  2. Check with the sender another way, such as a phone call to a number you already have or by typing the company’s website address yourself.
  3. Forward it to us at [email protected] if you’d like us to check it. Attach it as a file if you can, or forward it as it is.
  4. Then delete it. In Outlook you can also select Report in the toolbar, then Report phishing, if you see that button.

Quick test: stop and ask yourself

  • Was I expecting this?
  • Does it want me to hurry?
  • Does it want a password, a code or money?

If the answer to any of them is yes, stop and check first.

If it doesn’t work

  • You aren’t sure whether an email is real. That’s the right time to ask us. A genuine sender will wait.
  • You clicked or opened something. Don’t panic. Follow “I clicked a suspicious link: what to do now” straight away.
  • You entered your password on a page you now doubt. Change your password straight away (see “Reset your own Microsoft 365 password“) and tell us.
