Draconian Rules

I have a fairly specific outlook.com to the work I do, and as much as I set up rules to delete unwanted email its a losing battle.

Ive got over 100 rules, and Im no longer keeping up. 

Is it possible to set up a rule that deletes everything, and then sets up rules with a greater priority for specific emails I want to let

through? Along the lines of:

Rule 1 - move email from abc.com to inbox

Rule 2 - move email from xyz.com to inbox

Rule 3 - if the email is from someone else, delete it

I seem to remember that rules cant be directly used in this way, but Im wondering if you can specify them in a manner that

does the above (or something similar)

Thanks1
