This section provides solution articles for Veeva Vault Domain Settings issues. A company using Vault can have one or more domains and a domain can contain one or more vaults. Domains with more than one vault are often called “multi-vault domains.” With multiple vaults in a single domain, you can switch between vaults without logging out and logging in again, as long you have access to both vaults. In a typical setup, a customer has one domain that contains all of their production vaults and one domain that contains sandbox or training vaults. In each Vault user name, the domain is everything after the @ symbol. For example, the user firstname.lastname@example.org is on the veevapharm.com domain.
