I just bought the zoho mail service today, and I can't found where to add more users, it remind me:

Max user license limit reached. Please purchase/upgrade license to add more user(s) with mailboxes.

but in the price page:

How does the '/user' pricing work? Is it the same as paying '/mailbox'?

One user corresponds to one mailbox of 5, 10, 15 or 25 GB based on the base plan you choose. However, a user can have many email or domain aliases (ie. different email addresses), with all emails accumulated in the exclusive mailbox assigned to the user.

plz advise.

thx.
