Microsoft Outlook services began restoring normal operations on Friday morning, but many US organizations still faced disruptions. The outage started at approximately 1:00 p.m. Eastern Time on Thursday, interrupting email, calendar, video conferencing, and cloud storage systems. Local leaders in Miami, Maryland, and Los Angeles continued to advise residents that specific staff and services remained unavailable as of Friday.
Government agencies reported immediate administrative hurdles. The Arapahoe County detention facility in Colorado stated it could not process online bond payments. The office directed individuals needing to post bond for immediate release to appear in person at the jail. Similarly, the Los Angeles County Sheriff’s Department reported disruptions to its email and communications platforms. Emergency management services in Fredericksburg and Gillespie County, Texas, also lost email access and urged partners to call instead.
Utility providers in Maryland experienced delays as well. The Washington Suburban Sanitary Commission, which handles drinking water and sewer treatment, warned that technicians might be delayed by the outage. The agency noted that some customers could encounter difficulties paying water bills during the disruption.
Federal legislative work in Washington, D.C., also slowed. Congressional staffers operating during the lame duck session reported frustration over the timing of the outage. Some indicated they were in the middle of negotiating pending legislation and planning for the next Congress. Sharon Eliza Nichols, communications director for Representative Eleanor Holmes Norton, questioned whether officials should start conducting business via direct message on social media.
School districts across the country adjusted their communication channels. Districts in Richmond, Virginia, and Port Washington, New York, informed parents of the outage on Friday morning. They requested that families contact schools by phone or through alternative online platforms. The Albany school district confirmed it had restored its services. The Colorado School of Mines asked faculty to remain flexible with assignment deadlines for students unable to use Microsoft tools, although many of the university's systems run on Google Workspace and Canvas.
The disruption extended into the artificial intelligence sector. Anthropic, the developer of Claude, stated it was seeing signs of recovery but warned that some users might still receive errors. The company is preparing for a stock market debut with a valuation of up to $1.4 trillion. OpenAI reported it was investigating issues with Microsoft connectors that were degrading performance. The company said new connections might be broken and tools might not work as expected.
Financial markets also felt the impact. Workhorse Group, an industrial manufacturer, rescheduled its third-quarter earnings call, which was originally set for Thursday afternoon. Microsoft executive Charles Lamanna posted on social media late Thursday that there was no indication the outage resulted from malicious or cyber activity.
As of Friday morning, Microsoft reported improvements in service availability. The company warned that some users might still experience intermittent access issues or delayed email delivery while the recovery process continues.
