Microsoft 365 outage: what works and what doesn't

Is Outlook, your email or your calendar not working as it should today? Microsoft 365 is currently experiencing a global outage. Microsoft is rolling out a fix step by step and the first improvements are visible. In this article, you can read what is going on, what does and does not work, and how to carry on in the meantime.

What is going on?

Since Friday morning, 13 November 2026, part of Microsoft 365 has been disrupted worldwide. The problem lies with Microsoft itself. Because the fix is being rolled out step by step, it may already be working again for one colleague but not yet for another.

What is not working?

• Outlook and email
• Calendar, including in Teams
• Copilot
• Links in emails
• Planner and To Do

What is working?

• Calls in Teams
• Meetings in Teams
• Chat in Teams
• SharePoint
• OneDrive

How to carry on in the meantime

• Coordinate with colleagues via Teams chat instead of email.
• Is a meeting missing from your calendar? Ask the organiser to share the link via Teams chat.
• Your files in SharePoint and OneDrive are accessible as usual.
