Outlook users have reported difficulties with Microsoft’s January Patch Tuesday updates, forcing Microsoft, once again, to patch some of its patches.
Users reported that, after applying the January 13 Windows updates, some applications became unresponsive or encountered unexpected errors when opening files from or saving files to cloud-based storage such as OneDrive or Dropbox. In particular, certain Microsoft Outlook configurations with the PST file containing a users’ messages stored on OneDrive could cause Outlook to hang or lead to sent messages going missing or previously downloaded emails being re‑downloaded.
In response, Microsoft has issued a bunch of out-of-band emergency updates for Windows 11 and 10 and Windows Server 2019, 2022, and 2025 to solve the problem.
