New Outlook won't let me add my outlook email account.

I did not have any issues logging in, My org got me office 365 standard trial

Today when i logged in outlook.com (empty email) then went into Outlook (New) the first thing it does, is connect to the exchange server from outlook.com

Outlook.com is a dummy domain. It uses our domain that we don't use.

We removed the subscription, But now it seems as i am stuck with this. even when its removed from admin.microsoft.com, It will not let me login using Manuel settings anymore when it use to work.

It seems as we are bing punished for buying Microsoft 365. this is the second email that has been affected on our domain. we need to be able to either be able to clear data out of microsoft, Or microsoft has to come up with another way with auto-discovery or a option to auto check accounts or not.

My issue is exactly like this one:

I eventually got it to work, but I am not exactly sure how!
