Microsoft appeared to experience a significant service outage Thursday morning, with thousands of users reporting issues accessing their Outlook email accounts and other Microsoft 365 services.

The disruption affected users’ ability to log into their Microsoft accounts and access essential productivity tools.

According to the monitoring website Downdetector.com, more than 2,100 customers reported problems with their Outlook accounts by approximately 9:30 a.m. ET.

An additional 250 users reported issues across the broader Microsoft 365 suite, which includes office programs such as Skype and SharePoint, indicating the outage extended beyond just email services.

The primary complaint among affected users was an inability to log into Microsoft accounts, preventing access to email, documents, and other cloud-based services that millions of businesses and individuals rely on daily.
