MSFT stock traded at $508.51 before the bell at 10:56 GMT on Friday, down 2.77% from Thursday’s close, according to Yahoo Finance. That puts Microsoft within $3.51 of the $505 bear reference FinanceFeeds set when the shares closed at $545.18 on 9 November, with a Microsoft 365 outage that began around 1 p.m. ET Thursday still unresolved.
Outlook, Teams and Copilot failed for users in 74 countries, and Microsoft says it has no indication of malicious activity. Nasdaq-100 futures were flat over the same stretch, so the pre-market drop in MSFT stock is Microsoft-specific.
Outlook, Teams and Copilot Down in 74 Countries Since Thursday
Downdetector logged about 130,000 Outlook problem reports at the peak, with one tally reaching 138,058, CIO&Leader reported. Reports reached 74 countries and territories within about an hour, according to The Next Web. Microsoft tracks the incident as EX1550543 for Exchange Online and MO1550821 for the wider suite, per SecurityWeek.
Japan’s government IT infrastructure was affected, Singapore’s Government Technology Agency lost email, and the Philippine Supreme Court said its operations were affected, the Associated Press reported. EV maker Workhorse postponed its earnings call, and IndiGo and Air India rerouted customer email.
Microsoft Blames Unavailable Servers and an Overwhelmed Connection Process
Microsoft said the strain came from “a number of servers being unexpectedly unavailable,” with “a core process on affected servers” overwhelmed and “causing capacity loss,” according to Outlook India. At 01:48 GMT it narrowed that to the process “responsible for establishing secure connections,” ABC7 reported. A recent network configuration change coincided with the start, and Microsoft was reversing it to test whether it contributed.
Microsoft reported partial recovery at 04:36 GMT but said it had “not been sustained.” A later post said its fixes were “not taking as expected,” per AP. Charles Lamanna, Microsoft’s executive vice president for Copilot, Agents and Platform, wrote that “there is no indication this is the result of malicious or cyber activity.” Microsoft has promised a post-incident report once service is restored.
Anthropic and OpenAI Connectors Broke Along With Microsoft 365
Anthropic’s status page flagged elevated errors on its Microsoft 365 connector at 17:52 UTC Thursday. By 22:23 UTC it said the fault “is caused by a Microsoft 365 service incident,” with mail, calendar and search tools failing for most requests and Claude for Outlook also affected. OpenAI reported similar trouble connecting to Microsoft 365 tools, AP said.
Microsoft’s own Copilot Chat and Copilot access to work data were also hit. Microsoft said the outage affected Microsoft 365 offerings that interact with Exchange Online, per AP, and that mailbox layer is what both Copilot and the third-party connectors read from.

The ex-dividend date is also 19 November, per Yahoo Finance.
The fundamentals under MSFT stock were set before the outage, with Microsoft Cloud revenue up 30% to $63.9 billion in the September quarter and Azure up 48%. Microsoft spent $41 billion on capex in the June quarter, and the post-incident report will show whether a configuration change undid that capacity for a day. The next earnings report is expected around 27 January.
Investor Takeaway
MSFT stock is pricing the outage before Microsoft has published a root cause, with the post-incident report the next disclosure that can confirm or reverse the discount.
