REDMOND, Wash. — A widespread Microsoft service disruption Thursday interrupted Outlook, Teams and other workplace tools, leaving thousands of employees to confront a situation their calendars had never prepared them for: a workday without reliable access to work.
Outage reports climbed across the United States as users struggled to send emails, open accounts and connect to services. Microsoft said it was working to reduce the impact and restore functionality.
The disruption arrived in offices where nearly every task depends, directly or indirectly, on receiving a message about another task. Without new emails, some workers were briefly left with no obvious way to demonstrate that they were extremely busy.
Employees who normally spend the afternoon moving between Outlook and Teams could still perform their jobs in theory. In practice, that required locating files, remembering decisions and occasionally speaking to someone without first sending a calendar invitation.
Managers may have encountered the most difficult problem of all: how to arrange a meeting to discuss the fact that the meeting platform was not working.
The familiar troubleshooting ritual continued largely unchanged. People refreshed the screen, closed the application, reopened it, checked the Wi-Fi, and then asked coworkers whether the problem was happening to everyone else. It was, which offered temporary relief but did little to rescue the afternoon.
At least one productive activity remained available throughout the incident: telling another person, in considerable detail, that the software was down.
Normal service could return and the missed messages could arrive in a sudden flood. For office workers, this is the final stage of every interruption—the part where the unexpected free time is collected with interest.
