Several of Microsoft 365’s core cloud services experienced a major outage at the same time, affecting Outlook, Teams, Copilot, and more.

According to service status updates published by Microsoft, users experienced access issues with products including Exchange Online, OneDrive, SharePoint, and Microsoft 365 Copilot. Users in multiple regions around the world reported being unable to send or receive email, load their inboxes, or open files in the cloud. Microsoft said some infrastructure was experiencing unusually high load. Further investigation found that this was not caused by a general surge in traffic, but by a large number of servers unexpectedly becoming unavailable, putting greater strain on the remaining servers.

· Microsoft’s current explanation is that servers unexpectedly became unavailable, rather than a surge in traffic.
· The cause of the outage is still under investigation, and the materials provided do not disclose the progress of repairs.
