CLAUDE AI is reporting “major outages” amid global problems affecting Microsoft’s systems.
There are currently over 3,000 reports that Claude is experiencing problems on DownDetector.
On the Claude Status website, it reads that there are “elevated errors on claude.ai, Claude Code, and platform.claude.com.”
It continues to say: “We are investigating an issue with users authenticating to Claude.ai and Claude Code.”
The chatbot first identified outage issues at 5:52pm yesterday evening caused by the Microsoft 365 service incident.
Anthropic said at that point: “Requests to mail, SharePoint, Teams chat and calendar through the connector may fail, and new connections to the connector may not complete.”
At 10:15am today, there were 3,800 reports on DownDetector that the popular AI chatbot was not working.
By around 10:30am, DownDetector said there were around 270 problems currently on the Claude site.
Claude users have shared their problems on X, with one writing: “Did Claude just go down for anyone else???”
Others wrote: “URGENT. Claude is down around the world!!!” and “Is Claude down for everyone or is it just me?”
What do I do if the outage stops me working?

If you open your computer this morning and struggle to send or receive emails, Teams messages or access other Microsoft products, you may have been affected by the tech meltdown.
Before you spend the morning restarting your laptop, check with your IT team to see whether your workplace is affected by the wider outage.
If there’s a service-wide problem, tinkering with your computer’s settings is unlikely to be the best use of your time.
If Outlook and Teams aren’t working, use an agreed alternative — such as a phone call or text — to explain what you cannot access and which tasks are affected.
That might mean flagging a meeting you cannot join, a client you cannot contact or a deadline you’re struggling to meet.
Don’t assume your manager knows you’re stuck and be sure to look out for updates from your employer through other channels.
Then ask what you should do instead. Are there other jobs you can tackle? Should you stay available? When should you check back?
Outlook’s offline features may let you read previously saved emails, check calendar information or draft messages.
Just check with your manager first, and stick to your workplace’s data-security rules.
Sending confidential files to your personal email or uploading them to an unapproved app isn’t a safe workaround.
If you’re editing a local copy of a shared document, agree how your changes will be added back later — otherwise you could end up with several competing versions.
OpenAI, that owns ChatGPT, said it was seeing similar issues, writing: “We’re investigating an issue with Microsoft connectors where new connections may be broken and tools are not working as expected. We’ll share an update when we know more.”
Problems with Claude come amid a global outage of Microsoft’s main systems, seeing Outlook and Teams primarily impacted.
Schools, NHS Trusts, UK Police services and supermarkets are amongst some of the services reporting problems with its systems.
In the latest update issued this morning, Microsoft has said that “recovery actions are ongoing” as it continues efforts to fix the global outage of its Microsoft365 services.
Microsoft is also now saying it will extend its email timeout window to 48 hours “to help protect delayed messages while service recovery continues.”
