A notice from Microsoft regarding its service health status reported ongoing service degradation affecting Microsoft 365, warning that users may be unable to connect to multiple services. The outage also affected Guam, where at least one government agency reported disruptions.
A release issued Friday by the Governor’s Office on behalf of the Department of Public Health and Social Services said the department was experiencing a temporary email service disruption tied to the global Microsoft outage.
Microsoft attributed the disruption to a technical issue unrelated to cybersecurity or artificial intelligence agents. The company said the problem stemmed from an issue “during an earlier network capacity upgrade that surfaced following a recent network change.”
Microsoft said the underlying issue had been addressed and that it was working to restore service to remaining customers and regions. Because of the scale of demand, services are being restored gradually to allow stability to be validated at each stage, the company said.
As of 8 p.m. UTC Friday, affected services included Microsoft 365 services that interact with Exchange Online and email. Users may be unable to access their mailboxes through Outlook on the web or desktop applications, and email delivery may be delayed, according to Microsoft.
The disruption prompted DPHSS to advise residents to visit a department office in person for assistance or call to schedule an appointment.
“This includes individuals who have already submitted applications, documents, or service requests by email and require assistance during the disruption,” DPHSS said.
DPHSS said it will notify the public when email access is restored.
