Block or unblock senders in Outlook

This guide will provide instructions on how you can block an email address or sender from Outlook. This can be necessary for spam or other repetitious emails. 

Issue

You receive a marketing or spam email (or multiple emails) from a sender you no longer wish to receive.

Note, if you receive multiple marketing emails from a genuine company or organisation, there should be an 'unsubscribe' link in the email - only select this link if you recognise the company sending the email. This will take your email address off the senders mailing list. Please report spam email to the IT Service Centre by raising a ticket via the webform:

Resolution

1. In the list of emails, right click the email, click Block > Block Sender;

2. Outlook will then confirm the sender has been added to the Blocked senders list.
