Windows 10: How do I change my 365 account email to a personal domain email?

I keep getting an error message that says my email is associated with a school or business. I cannot update my 365 account with my primary email.

Can't send emails from my domain

I have tried to use GoDaddy's built in mail service which is based on Office 365, and I was able to send emails from the domain which were being delivered fine after a DNS change.
However, since switching back to my personal outlook.com account, I am unable to send emails once again.
Is this suggesting that the problem is on Microsoft's end?

 

Unauthorized Emails from my account?

It is more than likely that your email account was hacked, either by a virus sniffing your password, or just simply hacked.

Either way, change your password on your email account. Unfortunately the damage by already be done. They already have your contact list and your email address associated with that contact list. There is nothing stopping them from sending out emails using their own SMTP servers to everyone on your contact list and claiming the emails are from your email address. They don't actually have to have access to your yahoo account or even any yahoo server to send emails to people that come from your address.

 

Office 365 Outlook email accounts

The reason I am asking these questions are that two individuals are buying two new laptops and would like to share one Microsoft Office 365 Personal.
A has a subscription to Microsoft Office 365 Personal already and wants to share the same account with B.
I have installed Microsoft Office 365 Personal in a second pc B and when launching Outlook all my email accounts from A were loaded. So, I cannot figure out how to install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded.
This raises more questions for me.

1. So this
   • User A installs and activates O365 on User B's laptop
   • User B adds his / her email accounts to Outlook
   would not apply to Microsoft Office 365 Personal as it breaches the licence agreement?
2. Am I correct?
3. If it does apply how can I install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded, and I can only add B email account on the second pc?
4. Would B be able to access A OneDrive?
5. Or would B have a separate 1TB free space in One drive, or only the free 5GB or none at all?
6. And most importantly is this even legal or in breach of contract as Microsoft Office 365 Personal is for one user only?
