Change the primary domain
If you link multiple domains to your company, one of them will be your primary domain and the others will be alias domains.
You can create employee mailboxes only on your primary domain. An alias domain is an alternative name for your primary domain. Additional addresses on an alias domain are linked to a mailbox on the primary domain.
If you lose access to your company's primary domain or don't want to use it for some other reason, you can transfer the primary status to another domain. When you change the primary domain, your company mailboxes will be moved to the new primary domain. No data in mailboxes will be lost.
To make a domain primary:
Remove a domain
If your company has multiple domains connected, you can remove domains that aren't verified or the primary one:
- Log in to the administrator account for the company.
- Go to the Domains page.
- Choose the domain you want to remove.
- Next to the domain name, click Actions and select Delete.
To remove the primary domain, first set another domain as primary.
