Reset password to Admin center

Copper Contributor

Hello! New here, has not been able to find any similar thread.


Im trying to reset password to a customers admin center.
He still have the old email account, so he will get the code.

Now Office 365 asking to send a code to the old phone number.


How can he get the code without his old mobile number?

I am grateful for all the help for any help I can get

Hi Mathias

Sounds like they have two step verification set up

Logging in requires not only the username and password but also something like a code sent to the mobile number of their phone.

If they have lost/forgotten their number and/or lost their device there are two options. If you are a CSP provider and manage their tenant you should be able to go in through Partner Centre into the customers tenant and do the reset. If you are not a CSP and don’t have Partner Centre they will need to reach out to Microsoft Support in order to help resolve the issue (in this case get their verification number changed to a new mobile number or get two factor disabled on their account so they can get back in)

Hope that answers your question!

Best, Chris

@Christopher HoardThanks for the quick response.
They are a new customer.

I cant find any link to Office365 support if you cant login. Azure is easy but for Office365 i only get the home version when clicking on the support links. Do you have a link?

@Christopher HoardIt has now been resolved, the customer has received a response from Microsoft how to make changes to **** with his IT supplier to confirm that he owns the account. I got the feeling that he is still happy after contact with Microsoft.
