Microsoft reports mass outages in US, impacting customer accessibility

Software giant Microsoft has reported widespread outages of its Outlook and Teams services in the US. Nearly 130,000 users have reported disruptions. Software giant Microsoft on Thursday said it was working to fix widespread outages of its Microsoft 365 suite of apps — including Outlook and Teams — in the United States after more than 100,000 users reported disruptions, according to downdetector.com, an outage-tracking website.

The outage, which blocked users from accessing their e-mail and other services, also impacted Microsoft 365 connectors used by the companies OpenAI and Anthropic , which said tools were not working as expected. Downtracker said it had recorded outages to about 130,000 Outlook users just after 1 p.m. EST (1800 GMT), though the site noted the problem seemed to ease a bit later.

Some customers reported having trouble sending and receiving e-mail; others said the program was entirely inaccessible. Outages of the Teams workplace messaging app were also reported, as well as other Microsoft 365 services such as the AI assistant Copilot.
