People are heading over to Downdetector to report problems with Outlook, Microsoft's popular email and work platform. It was a slow rise in reports throughout the morning, with approximately 1,100 people making their way to Downdetector to report problems as of this writing. It's not one of those explosive outages we see with popular services, but it's high enough to make us take notice.

Microsoft's official status page shows "Service degradation" for consumer products, which would explain why things aren't working as expected. It has acknowledged that it's working on the problem, but it hasn't provided a timeframe for things to come back to normal.

Is Outlook down — live outage updates

Sign-in issues seem to be the most common problem I'm seeing reported across social media. And users are not happy.

"What a joke. Tell us in English what is wrong and what you are doing to fix it and an estimated timeframe. Stop pretending it is a small,issue," said one person on X.

On Down Detector, several people claimed the iOS app specifically was having issues.

"Each time I refresh a different outlook app fails. Hope they get this resolved quickly," a commentor wrote.

The Outlook subreddit is filled with posts trying to figure out getting around the sign-in issue and cursing out Microsoft.

Microsoft has another update and it appears more specific issues are occurring.

"We’re seeing specific errors related to authentication key failures. We’re working to determine the underlying cause in order to determine our next mitigation steps," the Microsoft Cloud Status says.

The page does say that you may experience intermittent sign-in failures or unexpected sign-outs.

Staying steady on Downdetector

While Microsoft has been busy reverting changes so users can log in to Outlook again, people are still hanging around on Downdetector reporting problems.

It has dropped slightly since the outage peaked, but it's still hovering around 1,400 reports, which is relatively high.

Another big update from Microsoft

Microsoft posted a fairly extensive update on its status page. Essentially, the company said that it has reverted a change and is investigating the problem.

"We've completed reverting the recently introduced change, however, this has not produced any relief. We're continuing to investigate the unexpected increase in error rates affecting two separate error scenarios to identify any potential root cause which may be responsible for this. Additionally, we're closely monitoring service telemetry to discover any other potential actions, or mitigation steps," said Microsoft on its status page.

Downdetector going up again

Downdetector reports are rising, reaching a record high of almost 1,500. Is this because more people are waking up and trying to get to work, or is something else going wrong? We're investigating, but Microsoft hasn't posted any new updates regarding the outage.

Everything else seems good to go

According to Microsoft's status page, everything besides Outlook is good. We're seeing some Downdetector reports for other Microsoft services, but those could just be users reporting the wrong service.

iOS seems to be the latest issue

Users in the Downdetector comments section are saying they can't get the iOS app to connect, which could be a new wrinkle in the ongoing outage.

What errors are we seeing?

According to Microsoft, the main issues users are seeing is intermittent issues signing in to Outlook.com. Specifically, they may experience intermittent sign‑in failures, including “too many requests” errors or unexpected sign‑outs.

If this is happening to you, then know you're not alone and Microsoft is aware of the problem and working on it.

The latest from Downdetector

The Downdetector reports are staying pretty consistent, fluctuating within the 1,000 range. Currently sitting at 1,173, it's the highest it's been so far, but not breaking out of the pattern too much.

Microsoft update

Microsoft posted an update on its Outlook status page. Here's what the company said: "We're reverting a recently introduced change to determine if this action provides relief from impact upon completion. In parallel, we're continuing to analyze customer reports, and we're closely monitoring service telemetry to identify our next steps and potential mitigation actions."

When was Microsoft's last update?

Microsoft hasn't posted an official update in a while, with the last one coming at 12:48 p.m. UTC (7:48 a.m. ET). That was more than an hour ago, which is pretty long for users waiting to access their email and other Outlook tools.

The company promised an update by 1:30 p.m. UTC (8:30 a.m. ET), but that time has passed without any new developments on Outlook. Hopefully, we get something official soon we can have a better idea of when everything will be back to normal.

A small downturn

While outage reports have remained mostly consistent, the most recent update shows a slight downturn. Sure, it's only a tiny drop, but it could be a sign that people aren't flocking to the service as quickly to report problems.

"We’re reviewing a recent change as part of our ongoing investigation and determining next steps," reads the latest update on Microsoft's status page.

Reports past 1,000

The reports on Downdetector have officially risen to more than 1,000, which isn't surprising, as the people on the East Coast in the U.S. are starting to wake up and get online.

Outlook.com is the main issue

"Users may experience intermittent issues signing in to Outlook.com," says Microsoft's status page.

This appears to be the main issue people are dealing with at the moment and if Microsoft knows what the problem is, hopefully the company can get the issue solved as quickly as possible.

On Microsoft's status page, the company says, "Service health information for Microsoft products and services designed for personal use by families, individuals, and students."

So it sounds like the ongoing outage is only impacting home users, and people who use Microsoft services for business should be okay, at least for now.

The reports start

It's been a slow rise in reports for Outlook, which could be explained by people in the U.S. just getting logged on. Either way, it's clear something is wrong with Outlook, and if things don't get fixed soon, we expect the number of reports to keep rising.
