Default Domain and Identity Issuer Azure Active Directory

My default domain on Azure Active Directory was created with my ISP name plus some random number plus sufix onmicrosoft.com (e.g.: my_isp876.onmicrosoft.com).

1 - What is the criteria to automatically give a name domain and identity issuer when we create an azure account?

2 - I added a custom domain, so how can I associated my user, the default user of Azure, with identity issuer of this custom domain for allow me delete domain created automatically?

3 - If it is impossible to do what was asked on item two, how can I fix that without lose trial subscription?

fix that means: To have one main tenant with domain name of my choice (could be onmicrosoft.com oe one of my personal domain).

Hi @llarruda • Thank you for reaching out. Please find my response inline.

1 - What is the criteria to automatically give a name domain and identity issuer when we create an azure account?

  • The only criteria I am aware of, for automatically generating tenant name is based on the email address that you use to create the Azure Account. E.g., if email address used for account creation is user1@example.com, the tenant name will be generated as user1example.onmicrosoft.com.

2 - I added a custom domain, so how can I associated my user, the default user of Azure, with identity issuer of this custom domain for allow me delete domain created automatically?

  • You cannot delete the default .onmicrosoft.com domain created for your tenant. However, you can use Set-MsolUserPrincipalName -UserPrincipalName username@my_isp876.onmicrosoft.com -NewUserPrincipalName username@customdomain.com command to change UPN of existing users.

3 - If it is impossible to do what was asked on item two, how can I fix that without lose trial subscription? fix that means: To have one main tenant with domain name of my choice (could be onmicrosoft.com or one of my personal domain).

  • To use .onmicrosoft.com domain name of your choice without losing trial subscription, you can login to Azure Portal > click on Create a Resource > Search for Azure Active Directory > Specify name of your choice and create a new tenant.

Once the new tenant is created, you can refer to Transfer an Azure subscription to the new Azure AD directory document to transfer your trial subscription to the new tenant.

Thanks, @amanpreetsingh-msft!

Just for bring some information, the name of default domain was the name of company name defined on Microsoft Teams associated with my Microsoft personal account. Just for coincidence is also my Internet Service Provider, just for that my confusion. Change domain of tenant affected Teams account also. Reading the documentation, but not with 100% assure, maybe others services affect this initial setting.

The choice of domain name should be explicit this settings at moment of creation of account, because only signing to try and already have to transfer subscription, deep dive in idiosyncrasies of platform it's not practical, since the option to set initial domain name will prevent that and allow learning about platform in a progressive way.

The cloud is unfortunately more complicated that some try to make it appear. There is no way to make complicated things easier, unless they won't be for everyone. Despite the zillions of trainings out there it is still individually very complicated to properly assess the proper training before dive deep in the clouds.
All this is to say that I also think it is probably not the best way to do the onboarding, but there is no perfect way. As soon as you take some time to analyse the way how everything works on Azure (and you should, I know well AWS and I told it should not be so different from it, but it is) you should be fine.
