Microsoft services disrupted in several countries, with thousands of reports involving Outlook, Microsoft 365 and Teams

A Microsoft service outage caused difficulties for thousands of users worldwide, affecting Outlook, Microsoft 365 and Teams.

Problems were reported in several countries, including the United States and Italy, and lasted more than an hour.

Data from Downdetector, a website that monitors online service outages, showed that by around 6:00 p.m. Italian local time, more than 130,000 reports concerning Outlook had been logged in the United States alone.

Reports continued to rise, so the number of affected users could have been higher. Downdetector also recorded more than 46,000 complaints about Microsoft 365 and around 3,000 reports from users unable to access Teams.

Microsoft confirmed that it had received reports from users having difficulty accessing their mailboxes through Exchange Online. In a post on the social media platform X, the company said it was investigating reports of problems accessing those mailboxes through various connection methods across the Americas.

The U.S. company began investigating the cause of the outage but had provided no further details at the time of reporting. Earlier, it had announced that a Teams issue affecting users in North America had been fully resolved.

After that announcement, Microsoft warned that the outage might also have affected connectivity to Microsoft 365 services in other regions.

According to NBC Chicago, the company also confirmed reports of difficulty accessing Exchange Online email through various connection methods across the Americas. The technical cause of the outage and the exact number of users affected have not yet been disclosed.
