Microsoft says it is aggressively pursuing all pathways to reduce impact as users across the U.S. experience outages accessing Microsoft 365 services through multiple connection methods.
According to the company, potentially impacted services include: Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot 365, and Microsoft Defender XDR.
Microsoft posted a statement on social media around 5 p.m. saying they were opening all available pathways to restore service, as all other action taken so far has not provided the anticipated relief.
“We found a core process on affected servers becoming overwhelmed, causing capacity loss. To validate a potential recovery, we’re isolating a portion of infrastructure, restarting affected components, and reintroducing traffic to confirm the services remain stable before applying the change more broadly,” the post said.
The company says as capacity is restored and clients across the nation reconnect, users may experience a gradual recovery of services.
Around 7 p.m., Microsoft posted an additional statement, saying that the servers they returned to service are becoming unresponsive once they receive traffic.
“We’re analyzing diagnostic data to determine what’s triggering the behavior. In parallel, we’re temporarily limiting which types of traffic can reach the affected infrastructure in some locations,” the post explains.
Additionally, Microsoft says it is rebuilding a subset of affected servers using a previous configuration to validate if this prevents them from becoming unresponsive.
The company is providing more information through the Microsoft 365 admin center, as well as at status.cloud.microsoft.
