Microsoft has been hit with a widespread global outage as users face disruptions across its online services including Outlook, Microsoft Teams, OneDrive and Copilot 365.

Outage-monitoring website Downdetector recorded a sharp spike in reports about 4.30am AEST, with more than 120,000 users reporting problems with accessing email platform Outlook.

The tech giant confirmed users may be locked out of a suite of services including Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot 36 and Microsoft Defender XDR.

In a statement posted to its Service Health Status site, Microsoft said it was working “aggressively” to restore access to the impacted platforms.

“We’re aggressively pursuing all pathways to reduce impact. As a precaution, we’ve paused all deployments and configuration changes while we review recent changes for any correlation to this event,” Microsoft said.

“We’ve determined that the elevated load isn’t driven by an overall increase in traffic, but by a large number of servers being unexpectedly unavailable, which is shifting load onto the remaining infrastructure.

“We’re investigating what’s causing these servers to become unavailable while we work to safely return them to service.”
