Notice: Disable Legacy Authentication for Accessing CityU M365 Email

In our ongoing commitment to enhance the security of the CityU M365 email system, the Computing Services Centre (CSC) has implemented Modern Authentication since February 2021. This is a significant step towards ensuring the safety and integrity of your email communications.

Please note that as of 27 March 2024, the legacy Basic Authentication (authenticated SMTP) for accessing CityU M365 email will be discontinued. Consequently, the ability to send emails via your CityU M365 alumni email from other email systems will no longer be available.

For those who access their CityU M365 email (OWA) via a web browser, rest assured that this change will not affect your email access.

For assistance and enquiries, please contact the IT Service Desk at 3442 6488, or via email to IT.ServiceDesk@cityu.edu.hk.
