A Microsoft 365 outage disrupted access to Outlook email services Thursday, and the company said users worldwide could have trouble connecting.
Microsoft first reported on X that users in the Americas were having trouble connecting to their Exchange Online mailboxes through several methods. Exchange Online is Microsoft’s cloud email service for businesses and other organizations. Outlook is one way users can access those mailboxes.
Microsoft said part of its infrastructure was under heavy load in several regions and that the strain was likely contributing to the connection errors.
The company said it had begun rerouting traffic across its global network to ease pressure on the affected systems.
Downdetector, a website that tracks outages through user reports, recorded more than 130,000 U.S. reports of Outlook problems at 1:27 p.m. Eastern. The site also recorded more than 46,000 reports of problems with Microsoft 365.
Thursday morning, Microsoft acknowledged similar issues with its Teams program’s functionality, though those problems appear to have been mostly resolved.
