Please see the section on 'Third-Party (Unsupported) Email Clients' below.

Use of third-party email clients unfortunately cannot be supported by the University, so if, after you update to the latest version of it, your one doesn't work with modern authentication, you should please liaise with the manufacturer of the client and, in the meantime, use the Office 365 web interface at to access your email. As part of the University's Office 365 suite of services and applications, Outlook fully integrates and supports modern, more secure authentication. If you are currently using a third-party client for your email, we strongly recommend you download Microsoft Office as above.

Open Outlook and set up your Office 365 account as per the instructions at Add an email account to Outlook.

If you don't already have it, please visit to acquire and install Microsoft Office.

Install Microsoft Office (includes Outlook) You can recognise an email client still using basic authentication as follows: It is import to update before the deadline, as after that the email client in question will no longer be able to connect. Our logs show you currently use an email client, most likely on a personal (non-Uni-managed) device that is connecting to University Microsoft services using the old 'basic authentication' method. Service Alert on deprecation of basic authentication Why have I received an email on this? January 2023 was the original projected period for the disabling of basic authentication, but this was brought forward to begin from the end of the first week of December 2022. The turning off basic authentication is not a School or University decision, but is being applied globally by Microsoft. It is being replaced by so-called 'modern authentication', whereby the username and the password are encrypted and sent separately, thereby being more secure. This method of sign-in unfortunately makes it easier for attackers to capture user credentials. 'Basic authentication' is where an application sends a username and password with every request. At the end of 2022, Microsoft disabled 'basic authentication' for University services.
