That's a nice theory, but we don't have office 365 and I didn't create the account haha.

The 'non-company' account is created manually by signing up for a new microsoft account and then clicking the activation link in the email you receive.

The school/work account is somehow created by a company administrator, but I don't know exactly how or where.

This sounds right. So this prompt is essentially asking me to tell them which buttons my boss pressed when he created my account.
