Microsoft confirmed a widespread Outlook/Exchange Online outage affecting thousands of users. The company said the disruption stemmed from an authentication component issue and is testing a remediation strategy before a broader rollout. The spike in problems began around 11 a.m. ET and persisted for several hours across multiple Exchange Online features such as mail delivery, search, and login. Reports also indicated partial outages of OpenAI’s ChatGPT Work services during the same window, complicating workflows for users relying on integrated tools. Coverage from multiple outlets highlighted the outage’s impact on business communications and the ongoing diagnostic and restoration efforts. Officials cautioned that status updates and regional impact could evolve as teams work to restore full service.
