Major Microsoft Outlook Outage Leaves People With Email Jobs Unable to Email

Around 10:40 am ET on Thursday morning, Microsoft posted on its 365 status page on X that it was “investigating reports of users experiencing issues when accessing or using Microsoft Teams functionality in North America.” By just before 1pm ET, it said it was aware of “issues accessing Exchange Online mailboxes through multiple connection methods in the Americas.”

Microsoft later said that its network was also “experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors,” but that the issue was related to servers going offline, not due to increased traffic.

Around an hour later, Microsoft said it had “begun redistributing connection traffic across our broader worldwide infrastructure to help balance the load” and was “aggressively pursuing all pathways to reduce impact.”

“We've paused all deployments. We're moving additional traffic off the affected infrastructure, and we're restarting affected servers to return them to service,” Microsoft wrote.
