The city said in a statement Friday that the disruption had no current impact on public safety. Microsoft had not provided an estimated time for restoring service, the city said, adding that it was in contact with the company and would share updates as they become available.

Residents were asked to be patient with other inquiries. City service tickets and information requests can still be filed by calling 630-CITY or visiting myjax.custhelp.com, and anyone facing a public health or safety emergency should call 911.

The outage affected a broad range of Microsoft 365 services that interact with Exchange Online and email, according to Microsoft. Users reported problems with Outlook, Teams and Copilot. More than 130,000 users reported Outlook issues to Downdetector at the outage's Thursday peak, though reports later declined.

Microsoft said it was working to identify the cause and repair affected infrastructure, and that it had no indication the outage was caused by malicious activity. In a later update, the company said changes intended to improve service were not working as expected.

The disruption extended beyond the United States. Government agencies in Singapore, the Philippines and Japan reported impacts, while companies including Workhorse Group and airlines in India reported email-service disruptions. Air India said its flight operations were unaffected.

Australian Home Affairs Minister Tony Burke said Microsoft had compared the incident to the 2024 CrowdStrike outage, which was linked to a faulty software update. Microsoft has not confirmed the cause of the current outage.

For Jacksonville residents, the disruption is a reminder of how deeply everyday government services depend on a handful of cloud providers. City officials did not say how many employees or departments were affected, but urged the public to use phone and online channels for routine requests while email systems are restored.
