Share Google Apps services with another domain
Do you have users in multiple domains who want to share and collaborate using Google Apps for Work? For example, a company with the domain mycompany.com might acquire another company at the domain newcompany.com. Employees at each company want to have an email address and account at their respective domain, and they also want to share Google Apps services with each other.
To let users share services across domains, you need to add the new domain as a separate domain and then add user accounts to it.
- You must own the domain name you add and verify your ownership.
- You can't add a domain that's currently associated with another Google Apps account. You must first remove it from the other account.
- Sign up for Google Apps for Work using your primary domain.
- Add another domain you own as a separate domain, not a domain alias.
- Add users and select which domain to add them to.
Each user gets an email address (if you're using Gmail) and username at the domain you add them to. They sign in to their account with this username so they can synchronize services across devices, meet in Hangouts, invite other users to Google Calendar events, and, in general, collaborate with other users. For details, see How to share.
For details on certain restrictions, see Limitations with multiple domains.
