    Hi PhilipBrosh, 

    Thanks for reaching out to the Microsoft Q&A forum. 

    Based on the information you've provided, it seems you're encountering difficulty re-verifying a custom ___domain in a new tenant because the ___domain is still associated with a previously deleted tenant. Unfortunately, as forum moderators, we do not have access to internal systems or databases due to privacy constraints. To move forward, I recommend reaching out to the Microsoft Support team. You can contact them using the resources below:  

    A support agent will be able to create a ticket under your current tenant and escalate it to the Data Protection team, who can help resolve the ___domain verification issue. 

    Note: Please have any relevant details about the old tenant ready—such as the tenant ID, ___domain name, associated email addresses, and any previous support case numbers. This information will help verify your ownership and speed up the resolution process.

    I hope this helps clarify your situation and guides you toward regaining access to your accounts. Please feel free to ask if you have any other questions.
