Question

Cannot log in to new 365 Business Standard admin centre

Salome Posthumus 0

I have a personal Microsoft account. Yesterday I purchased a Business Standard account. I went through the verification steps, but once I logged out (as I was instructed to do) I could not log in again. Now I cannot log a ticket or cancel my subscription because I cannot log in to the admin centre. The call centre in South Africa is not routing calls through to an operator. There is no email address to contact. There seems to be no way to speak to a human. I am stuck in a complete loop and am extremely frustrated.

Hi @Salome Posthumus

To better understand how the Microsoft 365 tenant was provisioned, could you please confirm:

When you say you cannot log in, are you unable to complete the authentication process (such as MFA or verification) or do you not have the sign-in credentials for the Microsoft 365 administrator account?
Did you receive any Microsoft 365 welcome or onboarding emails after purchasing the subscription?
If so, do those emails contain a tenant name in the format @yourcompany.onmicrosoft.com?
During the purchase or verification process, were you provided with an administrator account (for example, username*@yourtenant.onmicrosoft.com*)?

This information can help determine whether the Microsoft 365 tenant was successfully created and which account should be used to access the Microsoft 365 Admin Center.

Hi Jayden

I received an email titled 'Your new Microsoft 365 Business Standard subscription is available', which contained a '@yourcompany.onmicrosoft.com' email address.

I then followed the link in the email to 'Set up subscription'.

I followed the steps, and was then asked to create a '@yourcompany.co.za' email address. I was then instructed to log out and log back in again to complete the process. I logged out, but neither the '@yourcompany.onmicrosoft.com' or '@yourcompany.co.za' email addresses are recognised as usernames.

I suspect there was a glitch in the verification process, but now I am completely locked out.

Where are you trying to sign in, exactly? Are you able to sign in at https://admin.microsoft.com ?

Thanks for your information.

If @yourcompany.onmicrosoft.com account or the @yourcompany.co.za account is not being recognized during sign-in, it is possible that the setup process did not complete successfully or that there is an issue with the account provisioning in the backend service. In this situation, you will need to contact Microsoft support team.

I know you have tried phone support, please try again with the script below. Please visit the following page and reach out to phone number via: Customer service phone numbers - Microsoft Support

From what I know, you will need to get past the initial AI system to reach the live support team. You can refer to the guide below for tips on how to get through more easily:

If you have tried phone support and it's not working, please follow this link to create a trial tenant: https://www.microsoft.com/microsoft-365/business/microsoft-365-business-basic?msockid=3eb6980b5c6860e63a588d0c5d1761d6 - after that you will be able to access to Microsoft 365 Admin Center to raise the ticket Please note that this is just a temporary business tenant, you can cancel once you regain the access from the original tenant. You will need another credit card to open a new trial tenant.

Assuming that you have already created an account after registering a free trial and you can go to Microsoft 365 admin center and click "Help & support" icon to raise your ticket.

Please mention that you are raising ticket on behalf of the affected tenant that you do not have access to.

On the other hand, if you do create the trial and it resolves the issue, please remember to cancel the subscription afterward to avoid any related charges.

Hi Jayden

I have already tried to phone with the prompt above. The problem is that the South African call centre numbers simply do nothing after the bot says 'One moment'.

I am also very reluctant to create SECOND account to fix the first, as I may then be stuck with two inoperable accounts.

This is honestly one of the most frustrating experiences I have had.

A local business is trying to raise a ticket for me on their own admin centre. I cannot believe that Microsoft makes things this difficult.

I understand that creating a second subscription may seem ironic, but it is often considered a last resort when all other options to reach Microsoft Support directly have been exhausted. This approach has worked for some users, although the process can be challenging.

Fortunately, you mentioned that you have another administrator willing to open a support ticket on your behalf. I sincerely hope you'll be able to regain access to your tenant soon.
