Changing the default @onmicrosoft domain

We recently have started to use sharepoint and noticed that the domain is our old business name.  It is using the @onmicrosoft.com domain.  Is there a way to change the domain that was created when we made the O365 account?  The main reason this is wanted is because our sharepoint sites will show the old company name, that was used to signup for O365, and not the new domain that we added.  If we share out a sharepoint site or folder to a client, having the new company name would be better.  Anyone have any thoughts on a way to change this, besides creating a new O365 account?

  • Yes it is possible now, to change or correct the fallback domain name with .onmicrosoft.com you can check the below link.

    You can also change or modify the existing SharePoint URL by following the below MS guide.

    Please understand the impact before changing the SPO url
