Microsoft Outage: Why Outlook, Teams and Copilot Went Down for Millions, and What to Do Now
Microsoft's global outage has knocked out Outlook, Teams and Copilot in 74 countries since Thursday. Here's what went wrong, where the fix stands, why it matters for South Africans and job seekers, and what to do while you wait.
If you opened Outlook this morning and stared at a spinning wheel for five minutes, you weren’t alone. Microsoft has been fighting one of its biggest outages in years since Thursday, 12 November. Email, Teams, Copilot and a long list of Microsoft 365 apps have been failing for people all over the world.
At the time of writing on Friday afternoon, it still isn’t fully fixed. Here’s what we know so far, what Microsoft says went wrong, and what you can do while you wait for your inbox to come back.
How it started
The first complaints were about Teams on Thursday morning. People couldn’t sign in, calls dropped and chats wouldn’t load. At first it looked like one of those small glitches that clears up before lunch.
It didn’t clear up. By early Thursday afternoon in the US (around 7pm our time), Outlook had become the main problem. Downdetector, the site where people log problems with online services, recorded more than 130,000 Outlook reports from the US alone. Microsoft 365 as a whole passed 46,000 reports. Those are huge numbers for a site that relies on people going out of their way to complain.
Then it went global, and fast. Downdetector says the disruption spread to 74 countries and territories in roughly an hour. By Friday morning, users in Asia and Australia were reporting trouble too. In Australia, the country’s spy agency and its federal police were among the organisations caught up in it. That tells you how deep Microsoft sits inside the systems governments and big companies run on every day.
One thing to keep in mind about those figures: Downdetector only counts people who bother to report a problem. The real number of people affected is almost certainly much higher. Euronews put it at millions of users who couldn’t send or receive email.
What’s actually broken
Email has taken the biggest knock. People have been dealing with:
- Outlook mailboxes that won’t open at all
- Emails stuck in the Outbox, or arriving hours late
- Exchange Online refusing to connect, whether through the app, the browser or a phone
- Teams sign-in problems, dropped calls and chats that won’t sync
- Copilot, Microsoft’s AI assistant, not responding
- Defender, Microsoft’s security platform, also hit
Microsoft said the problems could reach users in any region. So if you’re in Joburg, Durban or Cape Town and your work email has been acting strange since Thursday evening, this is very likely why.
So what caused it?
The first question everyone asks now is whether it’s a hack. Microsoft says no. The company told customers it isn’t aware of any malicious activity behind the outage.
Its explanation is “elevated load.” In plain English, part of Microsoft’s infrastructure was handling far more traffic than it should. Some servers went down and started failing the automatic health checks Microsoft uses to spot sick machines. Once those servers dropped out, the healthy ones had to carry their share of the work as well. That pushed even more of them over the edge. It’s a bit like a taxi rank where half the drivers go home and the queue just keeps growing for the ones still working.
Microsoft hasn’t said what caused the extra load in the first place. But Australia’s Cyber Security Minister, Tony Burke, gave a hint at a press conference. He said Microsoft believes the situation is in some ways like the CrowdStrike disaster of July 2024, when a faulty software update crashed millions of Windows computers worldwide and grounded flights. In other words, an update that went wrong, not criminals breaking in.
We’ll only know the full story once Microsoft publishes its official review, which it normally does after a big incident like this.
Where the fix stands
Microsoft’s engineers have been trying a few things. They tested a configuration change to spread the heavy traffic across more of the network, and they’ve been restarting affected services one by one.
It hasn’t been smooth. On Thursday night Microsoft admitted that some of its fixes weren’t working the way it expected. By Friday it reported a “partial recovery” in some regions, but said that recovery wasn’t holding everywhere. Later on Friday morning it sounded more hopeful, saying it was seeing positive results for stability and extra capacity, and was rolling the same steps out to more regions.
Teams seems to be in better shape than Outlook. Microsoft said it had sorted out the Teams problems in North America, although some people there still struggled to connect. Email is the part still dragging.
Why this one hits South Africa hard
Microsoft 365 runs a big chunk of South African office life. Banks, government departments, universities, call centres and small businesses all lean on Outlook and Teams. Microsoft even has two data centre regions here, one in Gauteng and one in the Western Cape.
We’ve been here before. In March 2024, undersea cable breaks between South Africa and Europe happened at the same time as a Microsoft 365 problem in Europe, the Middle East and Africa. Office workers across the country lost email and Teams for days, and services were only fully back by that weekend. This week’s outage has a different cause, but the lesson is the same. When one company holds your email, your meetings and your files, a bad day for them is a bad day for you.
There’s also a jobs angle that people don’t think about. Lots of South African employers still ask for CVs by email. If you sent an application on Thursday night or Friday, it may be stuck somewhere, or it may land on a recruiter’s desk a day late.
What you can do right now
You can’t fix Microsoft’s servers, but you can stop the outage from making your week worse.
- Stop hitting send again and again. Emails you’ve already sent may be sitting in a queue. Send them five times and the recruiter or client could get five copies once things recover.
- Check your Outbox when it’s back. If something is still stuck after services return, close Outlook fully and open it again. That usually pushes the queue out.
- Use another channel for anything urgent. A phone call or a WhatsApp message will get there today. Email might not.
- Job seekers, keep proof. Screenshot your sent email with the date and time showing. If a closing date has passed, that screenshot helps when you follow up. Where a company has an online application portal, use that instead of email for now.
- Save your work locally. If OneDrive or SharePoint is slow to sync, save important documents to your computer as well until things settle.
- Watch the official updates. Microsoft posts progress on its Microsoft 365 Status account on X. It’s the quickest way to know when the problem is really over, rather than guessing from your own inbox.
- Ignore “fix your account” emails and SMSes. Scammers love a big outage. Microsoft won’t ask you to log in through a random link to “restore” your mailbox. Don’t click.
The bigger picture
Honestly, the scariest part of this isn’t the outage itself. Big systems break sometimes. What stands out is how much of the world stops working when one company has a bad day. One overloaded part of Microsoft’s network, and spy agencies in Australia and small offices in Soweto end up with the same frozen inbox.
For businesses, it’s a good time to ask a simple question: if email went down for two days, how would your team keep working? A shared WhatsApp group, a phone list printed out, a backup way to send files. None of it is fancy, and it might save your Monday next time.
We’ll keep this story updated as Microsoft shares more about the cause and when everything is back to normal. In the meantime, if your inbox is still down, at least you now know it isn’t your laptop.
