It’s pretty obvious after their data grab with the new Outlook. They destroyed the built-in app which I used all the time just to try to get all of my emails.
The New Outlook(tm) is an Edge Webview to the cloud.
In the stupidest twist of fate, you cannot open Outlook offline, at all. There is no concept of "offline" in the New Outlook. I assume this is Microsoft forcing away the issues of the past of 50+GB OST files by making Outlook a glorified webmail client instead.
Oh, and Microsoft Teams? You can open that offline and it's got a full cached experience. Innovation at its finest!
