New trial Azure account linked to wrong MS account

I think the free trial cannot be moved to another MS account; it stays with the account that created it. The simplest fix is to add ur business MS account as Owner on that subscription, or create a Pay‑As‑You‑Go subscription under the business account instead.

An Azure free trial can’t be “moved” from one Microsoft account (MSA) to another, and the free trial offer is limited to new Azure users per person. Once a free trial has been activated on a personal account, the system typically won’t grant another free trial to a different account for the same individual.

To work with the business account instead of the personal one, use one of these approaches:

1. Keep the existing trial on the personal account and add the business account as a user
   • Sign in to the Azure portal with the personal MSA that owns the current trial subscription.
   • In Microsoft Entra ID, create or invite the business account as a user and assign it the appropriate role (for example, Owner or Contributor) on the subscription.
   • Then sign in with the business account and use the subscription via role-based access control (RBAC).
   • This doesn’t transfer billing ownership, but it lets the business account manage resources.
2. Use a pay-as-you-go subscription on the business account
   • Since the free trial is no longer available, sign up the business account for a pay-as-you-go subscription instead of a trial.
   • During sign-up, ensure the profile information (contact email, address, phone, credit card) is correct and not conflicting with an existing Microsoft account profile.
3. If the sign-up shows ‘You are not eligible for an Azure subscription’
   • Verify the Azure account profile details for the business account:
     • Contact email, street address, and phone number are correct.
     • Credit card information is correct.
     • There isn’t already another Microsoft account using the same information.
   • If the message persists, follow the guidance in the troubleshooting article and, if needed, contact billing support.

There is no supported mechanism in the provided guidance to reassign or “switch” the free trial itself from the personal MSA to the business MSA; instead, use RBAC to share access or create a new (non-trial) subscription under the business account.
