    Oracle EBS / Java issue University IT and Finance are aware of an issue impacting the use of Java within Oracle EBS. The issue is preventing users from launching Java, therefore limiting the functionality available to staff. We are working to identify a solution to this issue and hope to have this resolved as quickly as possible.

  2. investigating Jun 09, 2026, 03:22 PM UTC

  3. identified Jun 10, 2026, 01:00 PM UTC

    University IT and Finance are aware of the issue impacting the use of Java within Oracle EBS. The issue is preventing users from launching Java, therefore limiting the functionality available to staff and appears to be due of a recent update to the Edge browser released by Microsoft. We believe Microsoft has recognised this issue and have released a further update which resolves the problematic behaviour. Subsequently, this change will be applied to Edge/Oracle EBS in Horizon this evening. If the update does not resolve the issue, a workaround has been provided separately to allow users to continue working.

  4. monitoring Jun 11, 2026, 08:51 AM UTC

    The issue impacting the use of Java within Oracle EBS has been resolved. Microsoft has released a further update which resolved the problematic behaviour, and this was applied overnight. However, we are aware the file association that enables TSV files to be opened with Excel has stopped working. This is being investigated separately and should be resolved overnight.

  1. identified Mar 04, 2026, 04:15 PM UTC

    We are currently investigating a high volume of scam emails delivered to Cardiff University accounts. These messages use several tactics, including: •Prompts to call a phone number to claim an expensive tech prize. •Links to files with misleading names such as “Cardiff University” or “Cardiff University March 2026 Payroll Update”. •Sender addresses that may appear to come from within the University. Our security teams are isolating and removing these messages and blocking any associated malicious links or files. You do not need to report receiving these emails, but you may use the Report Message button in Outlook if you wish. If you have clicked a link in one of these emails and have entered your username or password, please change your password immediately and contact the IT Service Desk. Please continue to follow our guidance on staying safe (search on the intranet for scam messages), including checking whether you were expecting an email or shared file before interacting with it.

  2. monitoring Apr 08, 2026, 09:47 AM UTC

    The specific content of scam messages continues to evolve, but we are still seeing significant numbers of the same general formats: • A file has been shared with you on SharePoint • Someone is giving away a number of rare or high value items Please remember that some of the most important considerations when deciding whether to trust an email are: - were you were expecting to it receive it - can you verify that the sender is who they claim to be, and that you trust them - be very cautious about clicking links in emails, and even more cautious about clicking links or buttons inside documents - if you are prompted to enter your credentials, check that the site asking for them is the genuine Microsoft login site

  3. resolved May 08, 2026, 09:52 AM UTC

    Mailboxes may still receive an email notification that a file has been shared where the contents of the shared file attempt to trick you into entering your credentials into a fake login site. Please continue to follow our guidance on staying safe (search on the intranet for scam messages), including checking whether you were expecting an email or shared file before interacting with it. It can also be worthwhile checking the URL shown in your web browser address bar for any login screens. Where Microsoft handle the login, the genuine URL should begin with https://login.microsoftonline.com/
