Dear Microsoft Team.

We've recently undergone a demerger and separated from our parent company. As part of the separation, we took over the M365 tenant. We created and are owning the DNS records of new domain. It is added into the M365 tenant and made primary. The question however remains on the name of the directory. We want to get rid of the Entra id directory name of our parent company. In the attached screenshot is shown the navigation of the directory name i am talking about. This directory name appears in MS Teams, Intune company portal, and every M365 apps.

To test, I changed the directory name in my test environment and it works fine. But offcourse, i dont have all the third party apps or enterprise apps connected as it is a test environment. But I would like to check with Microsoft on what will happen if I change this directory name. To all the devices and apps that a user works on? Will it break anything? if yes, what is the best way to handle this situation.

Please note- i know Tenant to tenant migration is one way. But we want to avoid going that far. Please suggest.

    First thing I think of this:

    You may want to open a ticket with 365 support and get some assistance.

    OK, sorry, I didnt see that attachment before. So you referring only to the Tenant Display Name? In that case, there should be no functional impact as the domain itself is not being renamed.

    Hello @abi,

    Changing the tenant name in your screenshot will not have any effect on connected services as they will refer to an {tenant}.onmicrosoft.com or vanity URL. That field will change the directory name as displayed in the switch directory blade and also the name displayed to any service federating with that tenant.

    You can see the federated brand name using https://login.microsoftonline.com/common/userrealm/x@{tenantDomain}?api-version=2.0
