Microsoft has resolved a drag-and-drop functionality issue for emails and calendar items in classic Outlook that arose after the installation of the KB5050094 January 2025 preview cumulative update and the KB5051987 February 2025 security update on Windows 11 version 24H2 systems. The recently released KB5052093 preview cumulative update effectively addresses this issue. A temporary workaround for affected users is to disable the "Optimize for compatibility" setting in Outlook by selecting "Optimize for best appearance" under the General tab in Options. Microsoft has also addressed other Outlook-related issues and plans to enforce the installation of the new Outlook email client on Windows 10 devices starting with the February 2025 Windows security updates.
