In the tech industry, the technology giant Microsoft is currently examining an incident of widespread disruption that has rendered thousands of workers and organizations unable to use their core productivity tools like Microsoft Teams, Outlook, and Exchange Online. The outage, which started early on Wednesday, January 21, into January 22, 2026, saw a surge in reports on service-monitoring sites, including Downdetector. Users who were based all over the world complained about a whole series of problems, including "connection timed out" errors, as well as total inability to log into their Microsoft accounts.
What’s Affected?
The impact will differ from region to region, some services in particular have received the highest number of reported failures, in which case what is going wrong?
- Microsoft Teams - Users must not join their meetings, send messages to the desktop app, or maintain contact with it.
- Outlook & Exchange Online - Users get very slow on sending an e-mail reply and get several "404" errors when accessing Outlook on the web.
- Microsoft 365 Suite: Intermittent access problems with SharePoint, OneDrive for Business, and Microsoft Store.
Mobile Apps:
Reports indicate that Outlook on iPadOS (Version 5.2602.0) is particularly unstable, often being frozen or crashing immediately upon launch.
Microsoft's Response
Microsoft addressed the incident through its official @MSFT365Status social media page, noting that the company is “investigating an issue affecting Microsoft 365 services.” Initial internal telemetry indicates that the cause is potentially more rooted in a third-party networking problem than a failure in the Microsoft service environment. This suggests a possible issue with a large Internet Service Provider (ISP) or any routing fabric that interfaces users with Microsoft’s data centers.
“We believe the Microsoft service environment is still healthy, and that the incident was due to a third-party network issue,” Microsoft said in a recent update.
Continuing Battle for iPad Users
Some services came around to desktop stability late yesterday, but far too many users, particularly on iPadOS 26.2, still report Outlook was completely useless. IT admins have recommended trying the Safari browser for temporary relief until a targeted mobile app patch is released.
Timeline of the Outage
21 January 10:15 PM IST: Reports start to spread globally.
January 22, 12:30 AM IST: Microsoft determines there is a potential "third-party networking" conflict.
January 22, Dawn (Now): Services are said to be back on track, but thousands of users continue to report "latent" performance and login loops.
To know the latest details, admins are recommended to log into the Microsoft 365 Admin Center under incident ID MO1220495.
