If you purchased the Visionary or Professional plan with 2+ users, you can add sub-users (separate custom domain mailboxes) to your organization.
There are two types of users:
– Public (by default) and
– Private users
You can only access the mailboxes of your non-private (public) users. If you have set a user as private, you cannot undo this, and the mailbox cannot be accessed by the administrator.
To access public user’s mailbox, navigate to Settings -> Addresses/Users and locate the user you would like to access. Click on the “More” button (next to the “Add Address” button) and select “Login” from the drop-down menu. You will need to enter your login password for the admin account you are currently using.
