Dear Valued Customers and Partners,

Today, a large-scale global outage of Microsoft cloud services (including Microsoft 365, Outlook, etc.) has impacted our corporate email system. Microsoft has officially confirmed that this disruption was triggered by an erroneous server health check.

At present, our customer service and business teams are temporarily unable to send emails normally. Some in-flight emails may suffer delays or delivery failures.

Per Microsoft’s update, services are being restored in phases. Once the cloud services are fully operational, we will promptly process and reply to all backlogged emails.

We sincerely apologize for any inconvenience this may cause and greatly appreciate your understanding and support. Should you have urgent matters, please reach out to us through our alternative communication channels below:
