A widespread outage hit Microsoft platforms including Outlook on Thursday, leaving many users unable to send or receive emails. According to outage tracker Downdetector, more than 120,000 users reported problems accessing Outlook around 1:30 p.m. ET, while thousands also reported issues with Microsoft Teams, the AI assistant Copilot, and wider Microsoft 365 services.
Microsoft acknowledged the disruption on social media, stating it was aware of users "experiencing issues accessing Exchange Online mailboxes through multiple connection methods in the Americas." The company later said a portion of its infrastructure was "experiencing elevated load" that was "likely contributing to the connectivity errors" and that it would begin "redistributing" traffic to balance the load.
Earlier in the day, Microsoft said it had "successfully restored" problems related to Microsoft Teams in North America, though some users continued to report connectivity issues. The Redmond, Washington-based company did not immediately provide further information on the cause or expected resolution time for the ongoing Outlook and Exchange Online problems.
