Access to lost admin account O365 tenant

[Jeffrey Jeensma]

We try to move a domain to our own tenant but as you can see in the attachment we receive an error. 

The problem is that the original admin of this tenant most likely left the company a long time ago. Is there a way to find out who is the admin of a tenant you can't access?

Hi!

If there is no way to get the admin credentials or get them through a password reset on the other tenant, raise a ticket from your admin centre to Microsoft support and they will help you to move this domain over. This is a common occurrence and is supported!

Hope this answers your question!

Best, Chris
