Microsoft (NASDAQ:MSFT) suffered a global service outage affecting Outlook, Teams, and Copilot, with Downdetector reports peaking near 140,000.
The connectivity disruption follows a separate outage last month on the company's Azure cloud platform that also impacted workplace tools.
"We appreciate our customers' patience while we work to restore services as soon as possible," said a Microsoft spokesperson.
Microsoft stated that unexpectedly unavailable servers strained remaining systems and disrupted connections for AI partners OpenAI and Anthropic.
Following the announcement the Microsoft share price was unchanged at $523.
The disruption forced electric truck maker Workhorse Group (NASDAQ:WKHS) to reschedule its third-quarter earnings release from 12 November to 16 November.
Microsoft operates the Microsoft 365 cloud suite, providing email, calendar, and AI software tools to international businesses across the US, Japan, and Singapore.
