Microsoft confirmed a global outage on Outlook, affecting web, mobile, and desktop users, starting around 10:20 UTC (3:50 AM IST)
The disruption affects email, contacts, and calendar access, while other Microsoft 365 services like OneDrive and Copilot remain operational.
Microsoft is actively deploying a fix, expecting a gradual restoration by the next status update.
Microsoft Outlook is experiencing massive outages, leaving users worldwide facing disruptions. Microsoft has acknowledged the disruption via a post on its Office 365 Status Page and said that they have identified the root cause of the possible outage and are deploying the fix. They stated, “We’re applying configuration changes, restarting affected components, and additional validations are underway to confirm that authentication components are properly configured.”
SurveyAs reported on Downdetector, hundreds of users have complained that the outage has affected Outlook, making it inaccessible. They said that the email, syncing calendars, and sending or receiving messages are not working. Many users trying to access Outlook are seeing the “Something went wrong” error message.
The outage affected both enterprise and personal users, particularly those who relied on Outlook for remote work communications. Several businesses reported workflow slowdowns and missed meeting prompts.
Meanwhile, affected users have taken to X (formerly Twitter) to express their frustration over the Outlook outage. A user wrote, Seems Outlook has been down globally for multiple hours. Can’t log in on desktop or web or app. And no word yet from @Outlook or @Microsoft. Did you guys fire the social media manager that should be reporting on global outages to keep users informed? Or perhaps haven’t trained AI yet on how to do that?”
Another user tweeted, “Outlook and Hotmail are down worldwide…users can’t log in or access emails. Microsoft says a fix is being rolled out, but no ETA yet.”
Here are some of the users’ reactions shared on X.
Came all the way to X to find why Microsoft Email https://t.co/KxjrSm3dyY Service was failing. There was NOTHING there to tell me. So, here, dear world, is the information: pic.twitter.com/BGBaAbx0jS

Outlook crashed this morning and broke across phones, browsers, and the desktop app.
Microsoft says a fix is rolling out asap, but good luck planning anything in the meantime.
