Microsoft is currently experiencing a global outage affecting Microsoft 365 services, including Exchange Online, which underpins UniSC email. The incident began overnight and some staff and students may notice problems this morning.

What you may experience

• Difficulty opening Outlook or accessing your inbox
• Emails that are slow to send or arrive, or fail to send
• Intermittent problems connecting to other Microsoft 365 services

What is happening

Microsoft has confirmed the issue is within its own infrastructure, where a number of servers became unavailable and placed additional load on the remaining systems. Microsoft engineers are restoring the affected infrastructure and redirecting traffic to improve availability. Microsoft has not yet provided a timeframe for full restoration.

This is not an issue with UniSC systems, and no action is required to fix anything on your device.

What you should do

• If Outlook is unavailable, try Outlook on the web at outlook.office.com, as access may differ between the desktop app and the browser
• Be aware that emails sent during the outage may be delayed rather than lost
• For urgent matters, use Teams or phone where possible
• Please avoid logging multiple service desk tickets for this issue; we are aware of it and tracking it closely

Updates

IT Services is monitoring Microsoft’s progress and will provide an update when services are restored. If you experience issues that do not match the above, contact the Service Desk.
