Adding your Office 365 tenant domain to G Suite

You need to add your tenant initial domain (that one ending with “.onmicrosoft.com”) to G Suite when you are setting up the coexistence between Gmail and Exchange Online. We will need that to migrate your e-mails to Office 365.

 

Please follow the steps bellow:

  1. Sign in to your Google Admin console.
  2. From the Admin console dashboard, click More Controls and then Domains.
 001
  1. Click Add/remove domains.
 002
  1. Click Add a domain alias.
 003
  1. Type your tenant’s initial domain (the one ending with “.onmicrosoft.com”) and click the Continue and verify domain ownership button.
 004
  1. Copy the text shown to the clipboard. Keep this tab open.
 005
  1. Open a new tab and sign in to your Office 365 Admin Center.
  2. Expand Settings, click Domains and then click on your tenant’s initial domain.
 006
  1. Click on DNS settings and then on Custom Records to expand them and see the options.
 007
  1. Click on New custom record button.
    1. Select TXT (Text) from the drop-down
    2. Type @ on the field TXT name
    3. Paste the text from Google Admin console on the TXT value field.
    4. Keep the TTL at 1 Hour
    5. Click Save
 008
  1. Go back to the tab with the Google Admin console and click the red Verify button.
 009
  1. Once it finished the verification, you can click the Continue link.
  2. Sign out from Google Admin console and Office 365 Admin center.

    Hi Mate, Thanks for that. Quite useful. However what purpose does this give? How would the connectors work from G Suite across to Office365? Any tips and or thoughts.Thank you.

      Hello, Manju, thanks for the comment.Ultimately, the purpose is to allow e-mail redirection from Gmail to Exchange Online and vice-versa, which is essential in a coexistence scenario.We start with all mailboxes in Gmail. So, for each account to be migrated, we create a mail user in Office 365 that redirects all e-mails from Exchange Online to Gmail. When we start the mailbox migration, it becomes a mailbox in Exchange Online and a redirection in Gmail. This last part is the one that requires adding your domain to G Suite.Please reach me directly if you need additional information about how we do it at FastTrack Center. You can find me at emiguel @ the usual place.Best,Miguel

      Hello, DavidThere is no additional configuration beyond what is explained on the blog post. However, it applies to the tool we use for G Suite migration at FastTrack Center. That being said, it really depends on the tool you are using and what you want to accomplish.If you are talking about a FTC customer, please reach out to your FastTrack Engineer or FastTrack Manager. If that's not the case, send me an e-mail: emiguel at the usual place.Best,Euclides

    There's actually a faster way to achieve email coexistence with Gmail that I wrote about several years ago:https://blogs.technet.microsoft.com/undocumentedfeatures/2015/09/30/configure-coexistence-mail-routing-without-a-secondary-routing-domain/
