Microsoft outage hits Teams and Outlook users

Microsoft has said it is working to fix an issue which has left some users unable to access emails and its Teams collaboration app.

Users began reporting issues as the working week began on Monday, with many reporting problems with Microsoft’s Office 365 suite, the firm’s collection of apps for personal and business users.

Investigating

Many reported issues sending messages, as well as loading attachments on emails or saving drafts.

Microsoft said in a post to X, formerly Twitter, shortly after, that it was aware of an issue “impacting users attempting to access Exchange Online or functionality within Microsoft Teams calendar” and was investigating.

We're investigating an issue impacting users attempting to access Exchange Online or functionality within Microsoft Teams calendar. For more information, please refer to MO941162 in the admin center.

The technology giant has since said that it has identified what it believes is the issue and has now “started to deploy a fix”, which the firm said was “currently progressing through the affected environment”.

Manual restarts

It said it was also carrying out some “manual restarts” on machines that are in an “unhealthy state” as part of the recovery process.

By 2pm on Monday Microsoft’s own service status website said all systems were running normally again, although the company has not yet commented further on the status of the fix.
