November 27, 7:22 AM ET: The Microsoft service status page states that "everything is up and running" when it comes to Microsoft 365. The Microsoft 365 Status X account shared the "after a period of extended monitoring, we confirmed through customer reports and service health telemetry that the issue is resolved."

Microsoft 365, Outlook, and Microsoft Teams users were in for a rude awakening to start the week. Those services all top the charts at DownDetector, which indicates service outages by collecting user reports. Outages started earlier today around 8 AM ET but spiked closer to midday.

Some reports of issues occured earlier in the day around 4 AM ET, which is roughly when Microsoft started investigating the issue, but issues appear to have caused more problems starting around 8 AM ET. There's a good chance the spike in outage reports aligned with people signing on for work to start the week.

"We're investigating an issue impacting users attempting to access Exchange Online or functionality within Microsoft Teams calendar," said Microsoft on its official Microsoft 365 Status account on X (formerly Twitter). That comment came at 9:06 AM ET after outage reports started to rise.

Microsoft later mitigated the issue as it identified a fix. The tech giant was able to determine the cause of the outages and is rolling out a fix for the issue. That rollout is gradual, however, as outage reports continue to come in at DownDetector.

Microsoft shared that the patch had reached "approximately 98% of the affeccted environments" as of 11:51 PM ET.

This is an ongoing story, and we will update this piece as more information becomes available.

When will Microsoft 365 be back online?

Microsoft identified the issue causing the outages of Microsoft 365, Outlook, and Microsoft Teams. The company started rolling a fix out earlier this week but "targeted restarts are progressing slower than anticipated for the majority of affected users," according to Microsoft.

Microsoft faced delays in its recovery efforts but has since gotten services online.

The latest from Microsoft is that all Microsoft 365 services are up and running as normal.
