Microsoft users across the Americas ran into email failures and app errors on Thursday when a widespread outage hit Outlook and several other services in the company's productivity suite.
The disruption reached well beyond individual inboxes. State and municipal government offices in Alaska were among the organizations affected, according to a report by the Juneau Independent, and some had to steer the public toward the telephone instead of email.
Outlook Reports Spiked in the Early Afternoon
Problem reports on the outage tracking site Downdetector peaked at close to 130,000 for Outlook shortly after 1 p.m. Eastern time. The volume of new complaints dropped after that high point, but the issues did not disappear right away.
Users described being unable to send or receive messages, and some said their inboxes would not load at all.
Teams, Copilot and Microsoft 365 Also Hit
Email was not the only service in trouble. Thousands of people also reported problems with Teams, the company's workplace chat and meetings app, along with its Copilot AI assistant and the broader Microsoft 365 platform.
Microsoft said earlier in the day that it had restored Teams service in North America. Even so, some users kept reporting connection problems after that announcement.
Alaska Agencies Turn to the Phone
In Anchorage, the municipal government posted a notice on its website Thursday evening advising residents who needed to reach city employees or departments to call rather than email.
Other government agencies reported similar difficulties during the day, as did organizations outside the public sector. The situation illustrates how much day-to-day public service now depends on a single provider's cloud email.
What Microsoft Said Went Wrong
In social media updates, the Redmond, Washington-based company said users in the Americas were having trouble reaching Exchange Online mailboxes through several different connection methods.
Microsoft said part of its infrastructure was under heavier than normal load, which it believed was likely contributing to the connection errors. It also found that a number of servers had unexpectedly gone offline after failing automated health checks.
The underlying reason those checks failed was not immediately clear. Microsoft said it was testing a fix and introducing an alternative way of running the checks so the affected servers could be brought back into service. "We're aggressively pursuing all pathways to reduce impact," the Microsoft 365 Status account wrote on X.
Why the Outage Matters for Businesses and Public Bodies
Outlook, Teams and Microsoft 365 sit at the center of daily work for a huge number of companies, schools and government offices. When those services falter at the same time, communication can stall across entire organizations.
Thursday's episode is a reminder that automated systems meant to keep infrastructure healthy can themselves become a point of failure. Organizations that rely heavily on one cloud provider may want to review backup communication plans, as Anchorage effectively did by pointing people to the phone.
For founders and IT leaders, the practical lesson is simple: know which tools your team would fall back on if email and chat went dark for an afternoon, and make sure customers know how to reach you too.
