Hello Carlos,

Welcome to Microsoft Community Forum.

I understand you want to migrate a google domain to Microsoft. Please follow the steps below to add a new domain to Microsoft 365:

1. Go to the Microsoft 365 admin center.
2. In the Microsoft 365 admin center, in the left nav, select Show all > Settings > Domains.
3. Choose Add domain, enter your domain name then select Use this domain.
4. Choose, Add a TXT record to the domains DNS records, select Continue, and copy the TXT value.
5. Go back to the Google Admin Console, choose Domains, Manage domains, View Details, Manage domain, DNS, and then scroll down to Custom resource records.
6. Open the record type drop-down, choose TXT, paste the TXT value you copied then select Add.

The update usually takes a fact within a few minutes but may take up to 48 hours.

1. Return to the admin center, select Verify,and then Close.
2. To set your domain as the primary email for your users, in the left nav, select Users > Active users.
3. Choose a user, select Manage username and email, Edit, select your domain from the dropdown, then select Done and Save changes.
4. Repeat this process for each user.

When you're finished, you'll be ready to install Office apps and migrate your email and calendar items to Microsoft 365.

You can also check the steps in this Microsoft article Connect your domain to Microsoft 365 for business.

I hope this information helps. If you have further questions on this matter feel free to ask I will be happy to continue working with you.

Kind regards,

Hello ChrisR_2112,

Thanks for your post here,

From your description, I understand that you would like to migrate G Suite mailboxes to Microsoft 365 and to move domain to Microsoft 365. Given this situation, Microsoft has provided an article with detailed steps to us. For your reference: Migrate consumer G Suite mailboxes to Microsoft 365 or Office 365. Therefore, you can follow the steps in this reference to complete your work.

Note: The migration won't migrate calendar and contact information, so please let the uses import them manually and they can refer to this article: Migrate email and contacts to Microsoft 365. Besides, all account owners must create an app password to access their account. This is because Google considers Outlook to be a less secure app and will not allow a connection to it with a password alone.

If you need more help, please feel free to let me know and I will try my best to help you.

Regards,

Seven

Microsoft 365 will never be your domain registrar nor bill you for your domain name. You can verify and add your domain to Microsoft 365 for using email/SharePoint service. See Add a domain to Microsoft 365
