To make it possible, we have to do migrate domain user’s emails to destination tenant before detaching domain from source tenant. Then we have to detach the domain from source tenant and attach the domain in destination tenant to keep the same domain name.
To successfully perform this task you will have to go through given different stages.

Stage 2 – How to Detach / Remove Domain From Office 365 Source Tenant
Before attaching domain into new Office 365 tenant we need to detach the domain from source tenant.
This step is necessary because we cannot access the same domain from two tenants.
Here, we are going to explain steps to remove the domain from Office 365 source domain.

Select the box which is next to user name who you want to move.

Choose how you want to verify that you own the domain.

Now, choose how you want to make the DNS changes required for Office to use your domain. Here, you have two options –1 – Add the DNS records for me – option for if you want Office to configure your DNS. 2 – I’ll add the DNS records myself – this option for if you want to attach only specific services of Office 365 in your domain. Here, we select I’ll add the DNS records myself (second option).
Now, click on Next, Now you can see the page with all records which you need to add your registrar website to setup domain. If you want to wait for that then scroll down & click on Skip this step.

Afterward, we have to move emails data from temporary users account to domain accounts, follow the stage 4.
Stage 4 – Move data into Destination Tenant to Destination Domain
Now, we need to migrate emails data which is stored in temporary mailboxes. But first, we have to create users mailboxes in the domain which is added in the previous step in the new Office 365 tenant.
After creating users mailboxes, you need to again use suggested tool to migrate users emails from temporary mailboxes into domain users mailboxes.
Example – tenant Name is tenant.onmicrosoft.com and domain name is domain.com. Consider, we have already migrated data into temporary users account [email protected]. Plus, we also created users mailbox in domain userA.domain.com in tenant. So, with the help of the tool, you will move users emails from [email protected] to userA.domain.com within the same tenant.
To perform this task you have to enter temporary users ID & password in source tenant and domain user ID & password in destination tenant.
After a few minutes later, you will get users emails into your new Office 365 tenant domain.
Sometimes, users need to move domain between Office 365 tenants or need to migrate a domain to a new tenant with users emails. But, there is no direct solution available to perform this task. However, With Detach & Attach procedure you can remove & add the domain, but, you cannot move users emails. Therefore, in this article, we have explained solution on How to move Domain between Office 365 tenants with users emails? With the help of above-given solution, you can migrate or transfer domain with users data between Office 365 tenants.
