Why did the global outage at Microsoft last so long? Will emails be lost?

Microsoft’s global outage disrupted Teams, Outlook and Copilot for roughly 24 hours, hitting schools, hospitals, businesses, courts and public agencies. Microsoft said the incident was not caused by a cyberattack and began restoring access after about a day, adding safeguards to prevent delayed emails from being lost. The disruption matters because the affected services underpin everyday communications for large organizations worldwide. What to watch next is whether Microsoft confirms full service restoration and explains the root cause.
