Microsoft issued another out-of-band update to fix a bug that caused Outlook to crash for Windows 11 users. This second emergency patch addresses issues seen with Outlook and files stored in the cloud following Microsoft's January 2026 Windows security update.

Thousands of Microsoft 365 users were reporting outages on Jan. 22. Here's the latest.

This comes just hours after reports that another emergency update has been issued by Microsoft to affect other problems besetting users, specifically Outlook becoming “ unusable .” And it comes a week after the first emergency update for January fixed failed shutdowns and remote logins. All told, a difficult few weeks for Microsoft.

Microsoft services are down for thousands of users, according to tracking service Downdetector.

More than 15,000 Microsoft 365 users weren't able to use basic functions Jan. 22 after the company suffered problems.

Microsoft and Amazon are rivals in the cloud, but on the same page when it comes to Washington's housing crisis — literally, in the case of a joint op-ed and full-page ad in The Seattle Times.

Microsoft stock is down nearly 14% from its all-time high.
