Microsoft has suffered an outage of its Exchange Online hosted email service that impacted users in the Asia Pacific region.
The issue was confirmed at 9.15am Sydney time from an official Twitter feed. Reports of issue resolution started around 40 minutes later and full restoration was confirmed by 11.15am.
"Investigating Exchange Online issue in APAC," Microsoft posted on its Office365 Twitter account.
"Some will not be able to connect to email. Resolving ASAP."
Microsoft urged users to check the Office365 service status dashboard for updates. The dashboard was available to registered Office365 users only.
However, several users including a Sydney-based systems integrator and an Adelaide-based SharePoint consultant noted the status did not show there was an outage.
Microsoft's primary Australian Office365 reseller Telstra referred questions on the outage to Microsoft.
A Microsoft Australia spokesman declined to comment, referring users to look at the internal dashboard.
Office365 last suffered a major outage in September last year that took the service offline for four hours. It was later attributed to a DNS issue.
