Microsoft 365 Outage Disrupts Swedish Municipalities, Universities, and Public Services
A global Microsoft 365 outage that began on the evening of Thursday, November 12, 2026, has left thousands of Swedish public-sector employees without reliable access to email, Teams, and other cloud services. As of Friday afternoon CET, recovery was under way with “encouraging” progress reported in Europe, though intermittent problems persisted and full restoration remained incomplete.The Guardian
The disruption, which peaked with nearly 130,000 Downdetector reports for Outlook and affected users in as many as 74 countries, primarily hit Exchange Online (the backbone of Outlook), Teams, Copilot, SharePoint, and related Microsoft 365 tools. Microsoft has ruled out a cyberattack, attributing the problems to a number of servers that became unexpectedly unavailable, overloading remaining infrastructure—likely linked to a failed or problematic server/network update or configuration change.Expressen
Widespread impact across Swedish public organizations
In Sweden, the effects were felt most sharply in local government. Huddinge municipality, which employs around 7,000 people, reported that staff could neither send nor receive email; the municipality directed the public to phone its switchboard (08-535 300 00) and stated there was no prognosis for when service would return.Huddinge
Södertälje municipality likewise experienced problems with email and its switchboard. Multiple other kommuner issued similar notices, including Jönköping, Sävsjö, Värnamo, Stenungsund, Tjörn, Orust, Karlshamn, Vallentuna, Varberg, and Lycksele. Many advised citizens to call rather than email.Sverigesradio
Region Stockholm reported that hospitals and acute care continued to function normally, with no major impact on clinical systems or telephony. However, intermittent Outlook and Teams issues affected administrative staff and some primary-care centers.Mitti
Universities were also hit. Karolinska Institutet warned of disruptions that could affect login and work in Microsoft services, while Luleå University of Technology reported limited access to Outlook and Teams.Expressen
IT security expert Marcus Murray of Truesec noted that the outage highlighted the vulnerability of broad reliance on a single provider: “It is clear that it has affected Sweden. This is an effect of everyone trusting the same supplier—it becomes vulnerable even though they have very good functions.” He added that email problems cascade to other services (for example, password resets) and warned of a likely wave of phishing emails once systems recover, as criminals often exploit such incidents with fake “Microsoft support” messages.Dn
Global scale and recovery status
The outage began in the Americas on Thursday afternoon US time and quickly spread. Similar disruptions hit healthcare, police, courts, and government bodies in the UK and elsewhere. Microsoft stated that emails sent during the outage should eventually be delivered and later extended the email timeout window to 48 hours to protect delayed messages while queues cleared.India Today
By Friday, the company reported incremental improvements and “encouraging recovery progress in Europe,” with better mailbox access and email delivery in parts of the region. Capacity had not fully returned to baseline, however, and some users continued to experience intermittent issues. Microsoft indicated it would publish a full post-incident report once resolved.The Guardian
The episode underscores the operational dependence of Swedish public institutions on Microsoft’s cloud platform and the practical challenges of maintaining continuity when that platform falters—even briefly. As recovery continued on Friday, many organizations simply directed staff and citizens to the telephone as the temporary alternative to Outlook.
