A Gmail user can grant mailbox access to another user in the same Google Workspace organization. The user granting access is referred to as the delegator and the user receiving the access is the delegate.
Delegates can read, send, and delete messages, as well as view and add contacts, for the delegator's account. See Set up mail delegation for more information about delegates.
Google Workspace organizations can use the
Delegates resource to
manage the delegates of accounts in their organization. This requires use of a
service account that has been
delegated domain-wide authority.
