Microsoft says Outlook access is recovering across Asia-Pacific, but email delays persist

Microsoft said Outlook email access was improving across parts of Asia-Pacific on Nov. 13, but acknowledged that some users could still encounter connection problems or delayed messages, according to Back End News.

In an update issued at 7:04 p.m. Philippine time, the company said recovery work on some affected systems in the region had been completed. More users were regaining access to their inboxes, and Microsoft was working through a backlog of emails waiting to be delivered.

Microsoft cautioned that service was not fully normal. "Some users may continue to experience intermittent issues," the company said, according to the report. Similar recovery efforts were underway in other regions, and Microsoft said it was adding capacity to stabilize operations. It had not declared all services restored.

What was affected

Beyond inbox access, the disruption touched several products that depend on Exchange Online. Most Teams functions — including calls, meetings, group chats and channel messages — were operating, but users could still have trouble viewing calendars, sending meeting invitations or rescheduling meetings.

SharePoint Online users could open stored files, though some had difficulty sharing them with people outside their organization. Copilot users could also face problems opening chats, receiving answers or using the tool to reach work email, calendars and files.

To manage the email backlog, Microsoft extended the permitted delivery window to 48 hours so queued messages would not time out before being sent. The company said some messages could take longer than usual to arrive.

No sign of malicious activity

Microsoft said it had found no evidence that malicious activity caused the outage. It plans to publish an explanation of what went wrong and what steps it will take to reduce the chance of a repeat once services are fully restored.

Why the region is watching

For businesses in the Philippines and Southeast Asia, Outlook and the Microsoft 365 suite underpin everyday communication, scheduling and document sharing. An outage that affects calendars and external file sharing as well as email can slow coordination between teams, clients and partners even when core messaging tools remain partly available.

The 48-hour delivery extension is a technical mitigation rather than a fix: it keeps queued mail from expiring, but does not guarantee prompt arrival. Organizations relying on time-sensitive email — approvals, transactions, service notices — may still see knock-on delays.

The report does not specify how many users were affected, which countries saw the worst disruption, or when full restoration is expected. Microsoft's account, as relayed by Back End News, describes an improving but incomplete recovery.

Until Microsoft publishes its post-incident explanation, the cause remains undisclosed beyond the company's statement that it found no evidence of malicious activity. That leaves open questions about the scope and duration of the disruption for regional users.
