Microsoft has released another out-of-band update to fix a bug that caused Outlook crash for Windows 11 users. This second emergency patch Addresses issues with Outlook and files stored in the cloud following Microsoft’s January 2026 Windows Security Update.
According to Microsoft, this update fixes a bug in which some applications that “open or save files stored in cloud-backed locations” became unresponsive or displayed error messages. Some users also experienced Outlook crashing or not opening when PST files were stored in cloud-based options like OneDrive.
This is the second time this year that Microsoft has had to release a last-minute patch for bugs related to its January security update. Last weekSome Windows 11 devices could not shut down or go into hibernation, while other devices running Windows 10 or 11 could not connect via remote connections. For more context, Microsoft only releases out-of-band updates when there’s a serious problem that can’t wait for its regular update cycle. Fortunately, the latest out-of-band update is cumulative, so simply download and install this one to resolve the issues you encountered with the January update.
