How to automate JCSC’s Suspicious Email Reporting Service

This guidance explains how to configure the Office 365 ‘Report Phishing’ add-in for Outlook, so that users can report suspicious emails to JCSC’s Suspicious Email Reporting Service (SERS).


This guidance is aimed at system owners responsible for administering Office 365 within organisations. Once configured, users can quickly report emails that they suspect to be phishing attempts, using a single mouse-click.

JCSC’s SERS automatically shares reports with the UK’s National Cyber Security Centre’s (NCSC) Suspicious Email Reporting Service: you do not need to do both. If you are based in the UK, you should use NCSC service here.

If you are based in Jersey, you should use this service. Using the Jersey service ensures we are able to analyse and respond to targeted attacks against Jersey and local industry.

The only configuration difference between the two services is the address to which suspicious emails are reported.

About JCSC’s Suspicious Email Reporting Service (SERS)

JCSC’s Suspicious Email Reporting Service (SERS) enables the public to report suspicious emails by sending them to

We use phishing reports to

  • identify and analyse trends in phishing activity
  • support threat intelligence
  • support our investigations into incidents

When you share a phishing email with us, the notification is automatically shared with the UK’s NCSC Suspicious Email Reporting Service. The NCSC analyses the emails and – if emails contain links to malicious sites – NCSC will seek to remove these sites from the internet so that the harm doesn’t spread.

If you have any questions about JCSC SERS and how we use your information, please contact

Please remember, this is an automated service. If you need our help with an incident, call us or email

When you report an email via SERS:

  • All the information you provide is held securely, with strictly limited access.
  • We will share all SERS phishing reports with NCSC in the UK.
  • To help understand and reduce the prevalence of online fraud and cyber crime, we may also share information derived from phishing reports with local partners such as the Jersey Fraud Prevention Forum, the Financial Intelligence Unit, and States of Jersey Police.
  • NCSC may share details with their law enforcement partners, such as the National Crime Agency and the City of London Police, to help identify investigation and mitigation opportunities.
  • For more detail on how JCSC handles information you send us, please see our Privacy Policy.
