Is there a safe way of importing old Windows Outlook Express files into new Mac Outlook?

Hi SergioDCQ,

To import old Windows Outlook Express files into new Mac Outlook app, you can use this:

1. Export Outlook Express data: On your Windows computer, open Outlook Express and export your data as .pst files. This will create a backup of your Outlook Express emails, contacts, and other data.

3. Use the Outlook Import feature: Open Outlook for Mac and go to the "File" menu. Select "Import" and choose "Outlook Data File" or "Outlook for Windows Archive File (.pst)." Browse to the location of the transferred .pst files and select the ones you want to import.
