Limitations with multiple domains

When you add a domain to your G Suite or Cloud Identity account, keep in mind some limitations with secondary domains and domain aliases. 

Tip: Google uses the name of your primary domain as the name for your organization as a whole. The organization name is referenced in the sharing options that users see. When you add domains, you might want to change your organization name to a more inclusive name.

Google Admin console

  • You can't directly set different policies or configuration settings for different domains. However, you can place users from each domain into separate organizational units, and then apply different policies to each organizational unit.
  • You can specify only one logo for your domains. The same logo appears for users in all domains that are part of your account.

Domain names and aliases

  • Domain aliases are automatically applied only users in your primary domain. For users in a secondary domain, you must assign the aliases in the Admin console or with the Directory API
  • G Suite account merge is not supported. Some current G Suite customers with multiple domains have separate G Suite accounts for each domain. Google does not currently support merging multiple G Suite accounts into a single multiple domain account.
  • Migration from domain aliases is not supported. Some current G Suite customers use domain aliases for their non-primary domains. Google does not currently support the conversion of domain aliases into multi-domain accounts.
  • Secondary domains are not available in the legacy free edition of G Suite. The legacy free edition of G Suite supports only domain aliases.

Google Drive 

  • You can't restrict sharing to a domain. Sharing options are based on the organization or organizational units. Learn about sharing options.

G Suite service URLs

  • You can't provide a global URL that users from all domains share. You must create custom URLs for your primary domain and each additional domain, for example, http://mail.primary.com and http://mail.secondary.com.

Google Groups 

  • If a topic is posted to the wrong group, you can move it to any other group in your domain. However, you can't move topics from a group in one domain to a group in a different domain. Learn more about moving topics between groups.

Google Sites 

  • Secondary domains can't be redirected to a "naked" URL. See more about Setting up a naked domain address
  • Search results include only the sites in a user's domain. For example, a user with an address in a secondary domain will not find sites created in the primary domain.
When you delete a secondary domain, all sites created on the domain are also deleted. To avoid data loss, copy all sites on the domain you plan to delete to other domains. For details, see Transfer a website to G Suite.
