Millions of people across the world have been unable to access Microsoft services, including their Outlook accounts.
According to Downdetector, people are having problems accessing the server connection, website and app.
The outage is also impacting Microsoft 365, Microsoft Teams, Microsoft Exchange and Microsoft Store.
The problems with Outlook were first reported around 8.30pm this evening and peaked at 9pm.
Microsoft said in a statement: ‘We’re investigating an issue in which users may be unable to access Outlook features and services. Additional details can be found under MO1020913 in the admin center.
‘We’re reviewing available telemetry and customer provided logs to understand the impact.
‘We’ve confirmed this issue is impacting various Microsoft 365 services. Refer to MO1020913 for more detailed information.’
Microsoft confirmed that it had now found a potential cause for the outage and is looking to alleviate the impact.
People have been very quick to vent their frustration about the outage on social media.
A person wrote: ‘So I’m guessing Microsoft Outlook is having issues, everyone around me has just been logged out of their emails.’
Somebody else commented: ‘I think Microsoft Outlook has gone down? Anyone else been signed out of Outlook or Hotmail?’
A third person sounded pretty desperate and wrote: ‘Hey. What’s going on with your software, no one can login to outlook and the error keeps saying too many attempts! What’s going on?’
A fourth even thought the worst had happened and added: ‘I thought I was getting my outlook hacked, turns out the entire Microsoft platform is getting hacked. Thank God it’s not personal.’
