Microsoft experienced a widespread outage on Thursday that disrupted Outlook email, Teams, Copilot and other Microsoft 365 services. Reports of Outlook problems reached about 130,000 on the outage tracking site Downdetector shortly after 1pm Eastern Time, with users unable to send or receive emails or access their inboxes. The figure fell to about 77,000 by just before 3pm. Microsoft said servers were unavailable and failing automatic health checks, creating pressure on remaining infrastructure. The company stated it was testing a configuration change to redistribute traffic and restarting affected services. Microsoft did not provide a timeline for full restoration.
