I am unable to access my Azure subscription due to a tenant and permission issue.

My situation:

  • I created an Azure Free Trial subscription
  • After adding a guest account / changing directory, I lost Owner access
  • Now I cannot access my subscription

Azure shows errors like:

AADSTS50020: User does not exist in tenant 'Microsoft Services'

Additionally:

  • I cannot create a support request from Azure portal
  • The support website keeps redirecting or not showing contact options

Request:

  1. Fix tenant login routing
  2. Restore Owner access to my subscription

Subscription: Azure subscription 1

Azure Role-based access control
Azure Role-based access control

An Azure service that provides fine-grained access management for Azure resources, enabling you to grant users only the rights they need to perform their jobs.

    Hello Anand Maharia,

    It seems like you are unable to log in to the Azure Portal due to changes made to your user account’s internal/external status in Azure.

    You originally signed up for the Azure tenant using your Outlook email address (******@gmail.com), which created an account in the format user123_gmail#EXT#@user123gmail.onmicrosoft.com. However, when you changed the account to an internal user, it was converted to @user123gmail.onmicrosoft.com. As a result, whenever you tried to sign in using your original Gmail email address (@gmail.com), you received the AADSTS50020 error because no tenant could be found for that account.

    I have shared the more details over private message. Please check and login with that UPN.

    You will be able to log in again using your updated internal account email address by signing in with your password and setting up Azure MFA.

    Hope this helps! Feel free to reach out for any further queries
