Microsoft has released a second “out-of-band” update to fix yet another bug introduced by its problematic January 2026 security patch. This latest emergency fix is for a bug that was causing Outlook to crash for some Windows 11 users.
According to Microsoft, the problem occurred when users tried to open or save files stored in the cloud, such as OneDrive. Some apps would become unresponsive or show error messages. For Outlook users, the app would crash or refuse to open if their personal storage table (PST) files were stored in the cloud.
This is the second time in as many weeks that Microsoft has had to rush out a fix for its January security update. Last week, a different bug prevented some Windows 11 devices from shutting down or hibernating and also blocked remote connections for both Windows 10 and 11 users.
Microsoft only issues these “out-of-band” updates when there’s a serious problem that can’t wait for the next scheduled update. The good news is that this latest patch is cumulative, meaning you only need to install this one to fix all the issues from the January update.
It’s been a rough start to the year for Windows users, but hopefully, this latest fix will finally put an end to the problems and get everyone’s computers running smoothly again.
