Updated at 3:47 p.m. CT:<\/em><\/strong>Microsoft’s official service health status page<\/a> has been updated to reflect what users have been reporting for hours: this outage extends well beyond Exchange Online alone.<\/p>\n

At the time of writing, Microsoft’s status page now lists a broader “service degradation” affecting Microsoft 365 for both Business and Enterprise customers, according to the company. The updated list of impacted services includes OneDrive for Business and SharePoint Online, Exchange Online, Microsoft Teams, and both Microsoft Purview and Microsoft Defender XDR.<\/p>\n

he company says it’s continuing to test its mitigation strategy to make sure the fix doesn’t introduce new problems, while also exploring other ways to reduce the impact in the meantime.<\/p>\n

In its latest update, the company said its investigation suggests a “misconfiguration issue” is stopping authentication components from deploying correctly to part of its infrastructure.<\/p>\n
