If you have a business account in Microsoft, and this account is used across a few Microsoft platforms, do Microsoft treat the account as one entity?
For example we currently synchronise our on site AD account to Microsoft Azure via AAD connect. If one of these users, uses thier domain account to also sign up for another service that is hosted within Microsoft Azure, a seperate tenancy for example, will any changes made to thier on prem account, after it has synced to our Microsoft tenancy also be reflected in the other tenancy as well. Such as a passord change? ie firstname.lastname@example.org
is part of our AAD and these details have also been used to sign into another service, backed by Microsoft Azure, but not part of our subscription.
