Using older versions of Outlook for Mac in business environments
This worked like a charm and really easy. Note that Ventura OS no longer has "System Preferences" - it has "System Settings" now, like an iPhone. This makes it harder to find Terminal.

Rest is as mentioned. Really easy and pretty fast indexing.
