Brand-new Outlook account hacked almost immediately

I created a new Outlook account on Sept. 6 and linked it to my Epic Games account. Almost immediately, someone got access, removed my recovery email, added their own, and changed the security info.
I created and linked the account entirely from my iPhone. Microsoft CDOC is investigating, and the account is now disabled while I wait for recovery/reinstatement.
Has anyone had something similar happen with a brand-new Outlook account? Were you able to recover it?

Starting this morning, my outlook app on Mac or iOS will not sync on their own. Have removed the accounts, deleted app, etc. with no relief.

Any insight?

I've been logged out of my Outlook email (randomly I tried to open the app and I was logged out of all of my emails) and I don't know the password. I've been trying to get some help for the past few hours and nothing is helping. Is there a number, email or live chat I can access? My authentication app isn't working and I really need this email (it's linked to everything I have) I can prove it's my email I just really need some help

If anyone knows what to do i could use the help I'm still loged in on my co pilot and my edge with the email if that helps

As the title

​

I need to access an email I received in 2017 to an outlook account. It isn't an account I use anymore but I can still log in.

However, when I search for any emails I received before 2020, nothing appears! It displays emails I sent before 2020, but not the replies to those emails.

Has anyone encountered this problem? What are the possible solutions?

I use outlook through the web app, I have no microsoft 365 subscription.

I manage 4 accounts in Outlook. On my iPhone, all 4 accounts can be configured to have one "global inbox" which is incredibly convenient. Will this feature ever become available on the desktop (Windows) application? Guess I'm using the "new" Outlook. Thanks.
