A global Microsoft outage is affecting some University systems, including Outlook, which is currently unavailable.
The University is actively monitoring the situation and will share updates via OxIntranet and status.ox.ac.uk (internal), the University website (external) and MyOxford (students), as those updates become available. Somerville College will also cascade updates via Teams.
What is working normally: Teams calls, meetings already in the diary, chats and channel messages are all working normally. You can also still open and edit files in OneDrive, SharePoint and Teams, but the “Recent files” list in Office apps may be empty. If so, go to the file directly.
What is affected:
- Email (Exchange Online / Outlook): Users may be unable to access, send or receive emails. Other systems and services that depend on email functionality, including automated notifications and workflows, may also be impacted.
- Calendaring: Users may experience difficulties accessing calendars, viewing availability, scheduling meetings or managing existing appointments.
- Microsoft Copilot: Users may be unable to access Microsoft Copilot or experience issues with Copilot functionality integrated into other Microsoft 365 applications, including SharePoint and OneDrive.
- Microsoft Teams: Users may experience disruption to several Teams features, including channel creation, Microsoft Teams Rooms, meeting scheduling and calendar integration. Some users may be unable to join meetings using the ‘Join’ button and may need to be dialled in by another participant as a workaround.
- Other Microsoft 365 applications: Additional services, including SharePoint Online, OneDrive, Microsoft Planner and Office Online, may experience intermittent connectivity issues, degraded performance or reduced functionality, particularly where features depend on other affected Microsoft 365 services.
The impact may vary between users and services.
Microsoft is actively investigating the issue and working to restore normal service. The University is closely monitoring developments and will provide further updates as more information becomes available.
There is a heightened risk of phishing attacks. Users should be vigilant for any suspicious calls or emails and avoid clicking unknown links, save work regularly, and check that any saved changes have been retained.
Updates for staff and students will be shared on OxIntranet and via Teams channels. The main University website is being updated. A further update will be shared by 2.30pm GMT.
