Hi @Collin ,
If the issue occurs when signing into the trial account, I would recommend confirming that this information is accurate:
- The information that you provided for your Azure account profile (including contact email address, street address, and telephone number) is correct.
- The credit card information is correct.
- You don't already have a Microsoft account that uses the same information.
To further troubleshoot issues when you sign up for a new account in the Azure portal, you can refer to the troubleshooting guide.
I have added the Office tag to this team since this is technically an Office product, but if you are still having any trouble, I would recommend contacting Azure the subscription support team by creating a support ticket with the Billing team (which is free).
