To Recover my M365 Business admin login credentials.

Question

To Recover my M365 Business admin login credentials.

Lakshmi Vellanki 0

I Have subscribed to an M365 Business Standard free trail, I have also received mail confirmation for active subscription. Now that I'm trying to login into Admin Center, I'm facing an issue. I don't remember my business mail/username and the setup I have initiated during Subscription. Subscription was done using my personal Microsoft account details which is restricting from accessing the M365 Business Admin Centre or else to recover the username credentials. Help me with login credentials of my Business Account. So that, I can get started.

Hi Lakshmi,

Thank you for sharing the details of your situation.

As this is a user-to-user support forum, I can only offer guidance based on similar cases. I do not have access to your tenant or account and cannot retrieve your login credentials. Only Microsoft Support can verify the tenant status, assist with Global Administrator or MFA recovery, and determine the available recovery options.

The personal Microsoft account used during the subscription process may be different from the business administrator account created for your Microsoft 365 tenant. To access the Microsoft 365 Admin Center, you need to use the business account associated with the subscription, which may look like ******@xxxx.onmicrosoft.com.

Please check the personal email address you used as the billing or contact email when activating the Microsoft 365 Business Standard trial. Microsoft may have sent a welcome or confirmation email containing:

Your initial administrator username
Your tenant domain, such as xxxx.onmicrosoft.com
Or you can search your inbox and Spam or Junk folders using keywords such as “Microsoft 365,” “Office 365,” “onmicrosoft.com,” “Welcome,” and “Your account.”

You may also refer to this article: I forgot the account I use with Microsoft 365

If you find the business username, try signing in at https://admin.microsoft.com. and complete the remaining setup steps to get started.

If you cannot find the login details or encounter an error when accessing the account, let me know and share a screenshot of the error message, if available, so I can provide the next steps. Please remove any personal or sensitive information before posting the screenshot.

I hope this information is helpful. Should you have any further questions or need additional assistance, please feel free to share them in the comment below. I'm very happy to help.
