Workers trying to log in to Microsoft<\/a> Outlook experienced unexpected problems Monday morning, with some users receiving error messages and unexpected signouts.<\/p>\n On its official Microsoft service status page<\/a>, the company confirmed that some Microsoft 365 Business and Enterprise customers were experiencing a service interruption and directed them to X for more information. <\/p>\n The Microsoft 365 Status page<\/a> on X stated that some customers were unable to log in to the email software. <\/p>\n \n “We’ve discovered some users may experience intermittent sign\u2011in failures, including ‘too many requests’ errors, or unexpected sign\u2011outs. We’re analyzing service telemetry further to identify any potential next steps and mitigation actions.”<\/p>\n Around 9:35 a.m. ET, the Microsoft 365 Status X account, posted a further update stating that the issues were ongoing.<\/p>\n \n Mashable Light Speed<\/span>\n <\/p>\n<\/section>\n \n The platform DownDetector<\/a> also reported a spike in user error reports beginning around 5 a.m. ET Monday morning, with a majority of users identifying login issues as the problem.
