Over 12 hours after outage people across globe still not able to access Microsoft Outlook, Teams

What happened

Microsoft 365 services, including Outlook, Teams and Copilot, remained largely disrupted more than 12 hours after an outage was first reported. Microsoft said it was investigating access problems with Exchange Online mailboxes and working to resolve server issues. The disruption continued into Asia-Pacific business hours.

Confirmed

Global impact / market context

When email and collaboration tools are unavailable, businesses and agencies can lose time handling routine work, potentially delaying customer service and internal decisions. A prolonged disruption can also increase pressure on Microsoft to resolve server problems and may affect confidence in its cloud services.

Analyst inference

The article describes a broad service interruption, with reports across regions and nearly 130,000 outage reports recorded by Down Detector at one point. It identifies Microsoft as still addressing server issues, but gives no financial impact, share-price movement, or estimate of lost revenue.

Confirmed

What to watch

1. Watch for Microsoft’s next update on the Exchange Online mailbox access issue and whether it confirms that Outlook, Teams and Copilot service has been restored. Analyst inference
2. Check whether Microsoft specifies how long the server problems lasted and which services or regions remained affected, since duration can shape customer disruption costs. Analyst inference
3. Look for any company disclosure of business impact, such as customer credits, lost revenue or added repair costs; the article provides no such figures. Analyst inference
