DO NOT UPGRADE TO "NEW OUTLOOK"
I would recommend not upgrading to "new outlook" - it is the worst implementation I've seen in over 30 years. It is not an "upgrade" to outlook it is a brand new application that really sucks. rules...
-- I can't go back because going to "new outlook" changed my mailbox.
Not sure I understand what "changed my mailbox" means. Can you give some more details please.
You should absolutely be able to switch back to Classic Outlook. There are numerous guides. e.g.
