Domain Force Takeover

[Chazak]

Hello,

Trying to add a custom domain to a new tenant gives me the error "We have confirmed that you own ***, but we cannot add it to this tenant at this time. The domain is already added to a different Office 365 tenant: ****

We no longer have access to the different tenant, how can I remove  or takeover the domain to use in the new tenant.

Tried https://docs.microsoft.com/en-us/azure/active-directory/users-groups-roles/domains-admin-takeover to no avail. Also used the PowerShell command for takeover force without success. 

How can I speedily resolve this?

Thanks

The takeover process only applies to cases where the domain was added because of "viral" subscription. If it was a "regular" registration in another tenant, you cannot use it and have to remove the domain from the other tenant. Contact support if you are having trouble remembering/getting access to the old one.

@Vasil Michev Thank you for a prompt response. I am not sure if it was a viral subscription or not.

I have contacted O365 Support and they have escalated to Data Protection but I haven't heard from them ever since. Is there another way to reach them?

You should have received an email with the contacts of the engineer, if not you can always call the generic line: https://docs.microsoft.com/en-us/office365/admin/contact-support-for-business-products?redirectSourc...

Thanks Vasil. Finally got the DPT to remove it.
