A small number of users have been receiving a security information prompt while using live@UCL OWA (Outlook Web Access). This prompt is a feature of the standard Microsoft service, and is used when userids and passwords are managed by Microsoft rather than the service organisation (UCL manages its own live@UCL userids and passwords). The prompt should be ignored, and you can simply click ‘save’ to access your email. 

We are awaiting a response from Microsoft why these prompts are appearing and will provide more information as soon as possible.
