Hourslong Microsoft outage disrupts Korean companies' daily operations

A global Microsoft outage on Friday disrupted daily operations for major Korean companies, leaving employees unable to access emails, coordinate with business partners, and manage workflows. The disruption affected multiple Microsoft services, including Outlook email, parts of the Teams messaging app, Microsoft 365 productivity tools, and the Copilot AI assistant.

While the impact varied by company, some employees had to postpone work or switch to alternative communication channels. IT industry officials reported that employees resorted to using other messaging apps for work, but the workaround offered only limited relief, as certain files could not be sent through these channels.
