Microsoft business data centres suffered access issues for nearly two hours following performance flaws in the US.
The cloud-based service for Microsoft's business clients in the US went down for almost two hours thanks to performance issues on Monday, news agency Reuters has reported.
The problem affected a few businesses in the region, preventing them from accessing the Microsoft data centre through the cloud.
"The outage was caused by a network issue that is now fully resolved, and service has returned to normal. We sincerely apologise to our customers for any inconvenience this incident may have caused them," Microsoft said in a statement.
The software giant had issued an early notice to its potential clients of timeouts with a number of its products and services, including the Business Productivity Online Suite (BPOS), Exchange Online, SharePoint Online, Office Live Meeting and Office Communications Online.
Also, among the services affected, was the Administration Centre, caused by a scheduled performance check by the service provider.
