Transfer ownership of domain owned by previous owners

Question

I have full ownership of domain slidedgeai.onmicrosoft.com and slidedge.ai

someone else has registered slidedge.onmicrosoft.com and registered slidedge.ai on it.

It may have been previously owned by them but now slidedge.ai belongs to us.

I want to link domain slidedgeai.onmicrosoft.com with slidedge.ai, but unable to register on Azure. It gives me an error "This domain has been previously configured on slidedge.onmicrosoft.com using an existing Azure AD or Office 365. To verify this domain name, you will first need to remove the domain name from the existing directory. Click here for more information."

So how do I remove slidedge.ai from slidedge.onmicrosoft.com?

Is there a way to find owner?

Answer 1

@Umaima ,
Apologies for the delay in response. I understand that you own slidege.ai domain along with slidedgeai.onmicrosoft.com tenant however it seems that there is another tenant with similar naming called slidedge.onmicrosoft.com which have registered the slidedge.ai domain on their tenant and you would like to know that how you can get slidedge.ai registered as a custom domain on your tenant slidedgeai.onmicrosoft.com .

In this case the easiest way is to contact Microsoft support .The owner information may be difficult to get unless Office 365 data protection team approve it . It is something that only Microsoft support can provide after verification of your domain slidedge.ai and in accordance with internal compliance rules as defined by the O365 data protection team.

Most of the times in these cases , we have seen that someone from within the company register different tenant by signing up for different Microsoft services like PowerBI , dynamics etc. for testing using their domain email. In your case someone with user@slidedge.ai may have done that I am assuming . These are possibilities but may or may not be true in your case.

If you have mailboxes with Office 365 and your email for slidedge.ai domain runs on Microsoft 365 services then you should be able to figure this out by checking the current administrators . If slidedge.ai uses Microsoft 365 email service and if you have your email configured with slidedge.ai domain means if your users use [user]@slidedge.ai email addresses then you can use the following instructions to find out global administrators of the azure AD tenant slidedge.onmicrosoft.com by using the instructions below.

You can use any of the user with [user]@slidedge.ai username and use powershell to get this info . Please follow the instructions below and you will be able to find out the name of the admins in your slidedge.onmicrosoft.com . You would require to download the azure AD powershell module from any windows 10 or above client and get the details using Powershell commands as below. Please check the linked articles for step by step instructions. You would need to install the Azure AD module using Install-Module -Name AzureAD if you do not already have the same. And once done you can use the script below to find your global admin.

 Connect-AzureAD  
 $role = Get-AzureADDirectoryRole | Where-Object {$_.displayName -eq 'Company Administrator'}  
 Get-AzureADDirectoryRoleMember -ObjectId $role.ObjectId | Get-AzureADUser  

If you are able to get the information of the administrator of this tenant then you can contact them via email and try to get them to remove the slidedge.ai domain from slidedge.onmicrosoft.com tenant . However if you do not use slideedge.ai as your email domain with Microsoft 365 mail service then the above may not work and in that case you would have to open a support case with Microsoft for further assistance.

Another thing you can check if your azure AD tenant was bought by any Office 365 reseller or you have any CSP who you buy azure services from . It may be possible that they may have some information as well. In the past I have seen some cases where the CSP was able to provide complete information in these scenarios. I would suggest to try that as well if you have CSP partner or any Microsoft contact . If not then again MS support is the last choice that I can think.

Hope this helps. If you find the information in this post as useful , please accept the post as answer which will help other members of the community searching for similar answers. If you have any further queries , please feel free to let us know and we will be happy to help further.
