Alibaba Mail sub-account capacity

Sub-account capacity management varies by the Alibaba Mail edition that you purchased:

• Alibaba Mail Standard Edition, Alibaba Mail Group Edition, and Alibaba Mail AI Advanced Edition are billed per account. Each account has unlimited capacity, and you cannot change sub-account capacity.

• Alibaba Mail Pay-as-you-go Edition is billed by total domain capacity and is no longer available for purchase. In this edition, you can set sub-account capacity freely in the domain management console. When you reduce the capacity of a sub-account, the new value cannot be lower than the capacity that the account already uses.
