New Outlook - Where is the option for the "Search Folders" where we can save searches ?

I cannot agree more. The new outlook search folder options are really pathetic and as long an they are not included, the new version is quite useless to manage your e-mail. I really do not understand why Microsoft decided to take out these features, for less advanced users there is always the option to hide this away so they do not need to bother...

Once CoPilot was available in "Classic" Outlook, I reverted back. I'm much happier with "Classic" Outlook. BTW, this is bringing back memories of the "New" Coca-Cola debacle and return of "Classic" Coke. Someone at Microsoft didn't pay attention during their Marketing classes.

The workaround that I've used is to set up a rule filter that apply a label to email that matches the search criteria. This way you can search by the label and find everything matching the criteria.

You can find the rule filters in:

Settings > Mail > Rules

Can you please post a screenshot? I am not seeing any of this! :)

if you go to the filter icon and click the drop down arrow and go to the bottom to more filters it will pop a search bar up at the very top. from there you can click in search and then there's more drop downs to the left and some suggested actions down low.
