Japanese media: When Microsoft 365 services went down, many companies had to bring fax machines back into use
IT Home, November 15 — According to The Japan Times, on the morning of the 13th local time, many employees in Japan clocked in and were about to turn on their computers to start work when a prompt popped up on their screens saying Microsoft 365 was inaccessible. Many had to reschedule meetings and appointments, and their work was disrupted.

One user posted on Platform X: "I couldn't open Outlook, and I panicked for a moment... I contacted my boss, and was told to stay home today." Another user wrote: "All the companies in our group rely heavily on Microsoft systems... the only thing we can do right now is go to the production floor and clean the coffee machines."
IT Home learned from the original report that many Japanese companies rely on the digital infrastructure provided by Microsoft. A survey by Keyman's Net last year showed that more than 78% of respondents' companies use Microsoft products.
Japanese Deputy Chief Cabinet Secretary 尾崎正直 has confirmed that Japanese government information systems were affected by the outage. Major credit card issuer Credit Saison issued a notice stating that due to a system failure in an external service, responses to requests received through the inquiry form will be delayed. Multiple universities, including Kyushu University and Waseda University, also reported that the service disruption affected their IT services.
Some Japanese workers were delighted at being unable to work, but others expressed anger over the resulting loss of productivity, stressing that fax machines are a reliable means of business communication. One user said on Platform X: "Microsoft's services are down and emails can't be sent, so we have no choice but to switch to fax to send the regular updates we usually send in PDF format. Analog technology is just reliable."
One social media user joked: "I thought this was simply heaven because I couldn't receive a single email. Turns out it was just Microsoft's services going down, so I was actually just queuing at the entrance to hell."
Ironically, the Japanese government tried to phase out fax machines as early as 2021, but faced strong opposition from bureaucrats. At the time, some even argued that fax is more secure than email.
