Microsoft suffered an outage on November 12, disrupting Microsoft 365 services, including Outlook and Teams, across multiple regions.

The company said high infrastructure load caused the problems after some servers became unexpectedly unavailable.

The outage began shortly before 1 pm. Downdetector showed about 130,000 reports from Outlook users, and Microsoft said the issues mainly affected Exchange Online, its hosted email service.

By 4 pm, Microsoft said a backup health check had brought some servers back online.

It was rolling out the change more widely and preparing automated systems to restart unresponsive servers.

Amazon Web Services said it was operating normally and that an unrelated internet disruption had prompted inaccurate outage reports.

The incident follows similar disruptions affecting Microsoft 365 services.

Microsoft documentation describes how partners can request a credit for qualifying online-service failures.

Separately, one industry analysis of the CrowdStrike-Microsoft outage highlighted how vendor consolidation can magnify operational disruption.
