On Thursday, a big Microsoft 365 outage left thousands unable to access Outlook and Teams, with the trouble starting around lunchtime.
About 130,000 users were affected before Microsoft said it was investigating reports of users experiencing issues with Microsoft 365 services, primarily issues with Exchange Online, and started rolling out fixes.
Microsoft is adding automated recovery tools
Microsoft found that an "elevated load" from several unavailable servers put extra strain on its systems.
By late afternoon, it used a new way to check service health, which helped get things running again.
To avoid this in the future, Microsoft is adding automated recovery tools that can spot and restart stuck servers.
Throughout the outage, it kept users updated on X as it worked to restore everything.
