Microsoft said there is no evidence of 'malicious activity', but investigations are ongoing and a full post-incident report will be released after mitigation is complete
A more than 12-hour outage of Microsoft Outlook and Teams crippled communications for businesses and governments globally on Friday, forcing some organizations to revert to fax machines and halting at least one bond repurchase in Europe. Microsoft said server issues were behind the incident that also affected its Copilot AI assistant and that a broader roll-out of software fixes was starting to stabilize the system. It said it was not aware of any malicious activity.
