Outlook for Mac 2019 - Search not working :-(

timsharpe 

correct. That works there. However, I have problems with the subfolders. They are empty there. The subfolders are also not displayed in one folder, but all one below the other.
E.g.

Main folder-A
_Subfolder-1A
_Subfolder-2A
_Subfolder-3A

Main folder-B
_Subfolder-1B
_Subfolder-2B
_Subfolder-3B

there it is displayed like this:
Main folder-A / _Subfolder-1A
Main folder-A / _Subfolder-2A
Main folder-A / _Subfolder-3A
Main folder-B / _subfolder-1B
Main folder-B / _subfolder-2B
Main folder-B / _subfolder-3B

Do you have any idea why the folders are displayed one below the other and how I can solve that?

timsharpe What happens is that "New outlook" has no local storage whatsoever. So it always searches on the server.

So, as long as all your email is on the server and you're online, search will work.

If you need to search historic inboxes in your local machine or you need to search while in offline mode, then New outlook is dead in the water for search.

Essentially it's equivalent to open outlook web and searching there (which already worked).
