Microsoft 365 recovers with Outlook back online

Resumen detallado

Asia Pacific infrastructure is remediated first.

Microsoft infrastructure and services have recovered after an 18-hour outage, with Outlook now accessible and the backlog of emails processing.

The cloud service provider said that it is “seeing encouraging recovery progress, with service availability and email delivery performance improving across a growing portion of affected Microsoft 365 infrastructure”, in a status update just past 11pm AEDT on Friday night.

iTnews was able to access Outlook for the first time all day, although scheduled emails sent during the day appeared hours out of order.

The breakthrough came at about 10pm AEDT, with Microsoft reporting success in its recovery efforts for “portions” of infrastructure in the Asia Pacific region.

It has also now reported gradual recovery in other regions, including the United States, which is just beginning its Friday.

"We’re seeing encouraging recovery progress in Europe, with service availability and email delivery performance improving across a growing portion of affected Microsoft 365 infrastructure," Microsoft said.

"Japan remains comparatively more stable, while North America is also improving; however, some users may still experience intermittent issues as recovery actions continue."

The vendor added that “reducing email queues and backlogs remains a priority.”

Microsoft has altered its typical email timeout window, extending it to 48 hours, “to help protect delayed messages as delivery catches up.”
