Microsoft says its recovery from a major global service disruption is making progress, with email queues significantly reduced and approaching normal levels. The update offers relief to businesses, public agencies and individuals who have faced problems accessing email and other Microsoft 365 services.

Recovery Efforts Show Signs Of Progress

The company’s latest update indicates that its engineers are making headway in restoring affected infrastructure and clearing the backlog of delayed messages. The Associated Press reported on Friday that Microsoft had seen improvements across North America, Europe and Asia-Pacific, although some customers were still experiencing intermittent access problems and delays.

The disruption began on Thursday, November 12, and affected Outlook and Exchange Online, alongside connected Microsoft 365 services. Depending on their reliance on Exchange Online, users also reported problems with Teams, Copilot and other workplace tools. Microsoft’s incident notices listed mailbox access and delayed email delivery among the principal impacts.

Why The Outage Had A Wide Reach

The incident demonstrated how closely linked modern workplace applications have become. When a core email and identity-related service experiences difficulties, connected products can also lose functions that depend on it, even if their other features remain available.

The Washington Post reported that Microsoft attributed the disruption to a network change intended to increase capacity, which left some servers unexpectedly unavailable. Recovery was complicated when some infrastructure returned to service but became unresponsive again under traffic. Microsoft has said it was not aware of malicious activity causing the incident.

Improving Email Queues Do Not Yet Mean Full Restoration

Although the reduction in email queues is an encouraging development, it should not be interpreted as confirmation that every affected service has returned to normal. Microsoft’s status updates have described recovery as a staged process, with engineers restoring capacity carefully and monitoring stability as traffic is reintroduced.

Users may therefore continue to experience intermittent sign-in problems, slow mailbox loading or delayed delivery while the remaining backlog is processed. Microsoft has also extended the email timeout window to help protect delayed messages during the recovery period, according to live reporting by The Guardian.

What Customers Should Do

Customers should check the official Microsoft 365 service health status page for updates from the company. Organisations should avoid assuming that a message has been lost simply because it has not arrived, and should follow their IT teams’ guidance before repeatedly resending important emails, which could create duplicate messages if the original is later delivered.

For organisations whose operations depend heavily on cloud email and collaboration platforms, the disruption is also a reminder to maintain alternative communication channels and documented continuity procedures. Phone calls, secondary email arrangements and other approved backup systems can help keep essential work moving during a technology outage.

Microsoft’s latest report of significantly reduced email queues marks a meaningful step towards recovery. The key test now is whether service capacity remains stable as normal traffic returns and whether customers across all affected regions regain reliable access.
