What initially started like a minor Microsoft Teams outage has also taken down multiple Microsoft 365 services with Teams integration, including Exchange Online, Windows 365, and Office Online.
“We’ve received reports of users being unable to access Microsoft Teams or leverage any features,” the company revealed on its official Microsoft 365 Status Twitter account more than 8 hours ago.
Teams was not the only product impacted by the outage since users also began reporting failures to connect to various Microsoft 365 services.
Microsoft confirmed the issues saying that the subsequent Microsoft 365 outage only affected services that came with Teams integration.
“We’ve identified downstream impact to multiple Microsoft 365 services with Teams integration, such as Microsoft Word, Office Online and SharePoint Online,” Microsoft explained.
After redirecting traffic to a healthy service to mitigate the impact, Redmond said its telemetry indicates that Microsoft Teams functionality started to recover.
