summary for non-techies**

The latest update in Outlook for Windows allows users to import .pst files directly into their mailbox, simplifying the management of emails, contacts, and calendar events by integrating previously separate data into one accessible location.

Direct effects for Operations**

Data Loss Risk
If users attempt to import .pst files without proper preparation, there is a risk of data loss or corruption, especially if the files are large or contain complex data structures.
