Changing initial .onmicrosoft domain name

Question

We recently split-off from a former company. The company I work for now assumed "ownership" of the Microsoft 360 account, and we pay for it. We have changed the name to our current company, but when I receive emails from anyone on our company email to my personal Gmail, the domain is listed as “formercompanyname.onmicrosoft.” I believe this has to do with our current Microsoft Office Suite licensing agreement.

How do I go about changing this to our new company name?

Answer 1

Hi Mck,

It’s not feasible to change the initial “formercompanyname.onmicrosoft” domain here after sign-up. To use a different onmicrosoft.com domain, you need to have a new subscription with Office 365.

Please refer to the following article:

About your initial onmicrosoft.com domain in Office 365.

If you do want to put your current branch company name into your Office 365 account and already have a domain of your current company, as a workaround, you can add the custom domain to this tenant and set up email and other Office 365 services for the current company users.

Add users and domain to Office 365

Thanks for your understating.
