Hi,
Thank you for sharing your question. I understand how stressful it is to purchase Microsoft 365 Business Standard and then be unable to log in, especially after multiple attempts and calls. Let’s go through why this happens and how to resolve it.
This issue often occurs when the new @onmicrosoft.com account was not fully set up or verified during the purchase process. If the account does not exist in the Microsoft Entra ID directory, you won’t be able to sign in or access admin features. The confirmation email you received indicates the tenant was created, but the sign-in failure suggests either the username is incorrect or the account setup was incomplete.
To resolve this, go to https://admin.microsoft.com and try signing in with the exact @onmicrosoft.com username and password you created. If it still says the account doesn’t exist, verify the tenant by visiting https://signup.microsoft.com and entering your business email to recover the organization account. If you cannot recover it, contact Microsoft 365 Business Support directly through the Get Help option at https://admin.microsoft.com or by calling the commercial support number listed for your region. They can confirm the tenant and reset credentials.
I hope this helps.
Best Regards,
Noel
