Microsoft Outlook experienced a widespread outage on Monday, leaving users across several countries unable to access their email accounts.
More than 800 users have reported a problem in the UK, while more than 400 people have said the same thing is happening in the US.
Reports indicate that the disruption was largely caused by failures in authentication systems, preventing users from successfully signing in.
Many were caught in repeated login loops or received error messages when attempting to access their inboxes.
According to outage tracking services, hundreds of users in the UK and the United States reported issues, with the majority կապված to sign-in problems and app malfunctions.
Microsoft acknowledged the issue, stating that some users were experiencing intermittent sign-in failures and unexpected sign-outs.
The company said it is investigating the problem and working to restore normal service.
The outage also affected other Microsoft 365 services, highlighting the heavy reliance on the platform for daily communication and business operations worldwide.
