HSE emails affected as global Microsoft outage hits Ireland

Microsoft has acknowledged that the recent changes implemented to address the ongoing outage are not functioning as anticipated. In a fresh update on X, the tech giant stated that the resolution is falling short of expectations and is actively exploring alternative approaches to rectify the issue. "We've monitored the status of the changes applied to improve serviceability and confirmed that change is not taking as expected," Microsoft 365 Status announced in its latest update.

"We're identifying alternate workstreams that can be applied to increase capacity in the face of sustained traffic management imbalances," the company added.

The Microsoft 365 outage has impacted a range of services, including email, workplace communication through Teams, and the AI-powered assistant Copilot. According to Downdetector, around 130,000 users globally reported issues during the peak of the disruption. Users have faced challenges accessing Outlook, sending and receiving emails, and loading their inboxes, while thousands have also experienced disruptions to Teams, Copilot, and other Microsoft 365 applications.

Initially, Microsoft was investigating reports of users encountering difficulties accessing Exchange Online mailboxes through various connection methods. The company later attributed the connectivity errors to an elevated load across a portion of its infrastructure, which had become unavailable after failing automated health checks. Microsoft clarified that the heightened load was not due to an overall surge in traffic, but rather the result of reduced server availability.

The company has provided additional information under case IDs EX1550543 and MO1550821 in the Microsoft 365 admin center, as well as on their website at https://msft.it/6013xBHsf for those unable to access the admin center.
