Reduce the Alibaba Mail account quota
This topic explains how to reduce your Alibaba Mail account quota.
Use cases
You may need to reduce your account quota if your organization purchased more accounts than necessary or due to business adjustments.
Solution
For paid editions of Alibaba Mail, you can reduce your account quota only through online services within 30 days before your subscription expires. A scale-in is not available at other times due to various factors, such as the purchase price and subscription term. You must use the Alibaba Cloud account that owns the mailboxes to scale in.
The Free Edition of Alibaba Mail does not support scaling out or scaling in.
Procedure
Submit a ticket to enable the scale-in feature. Once enabled, go to the Alibaba Mail console and select Mailbox List > Manage > Scale In.
After the scale-in feature is enabled, you must complete the scale-in within the 3-hour validity period. The feature cannot be enabled frequently.
The new account quota must be greater than or equal to the number of existing accounts. For example, if you purchased an account quota of 50 and have created 40 accounts, you cannot directly reduce the quota to less than 40. To reduce the quota below the current number of accounts, you must first back up and delete the excess accounts.
The account quota after the scale-in cannot be lower than the minimum purchase quantity for your edition. The minimums are 5 for Standard Edition, 10 for Premium Edition, and 100 for Group Edition.
For the Group Edition, you can only reduce the account quota in increments of 50.
A scale-in typically results in a refund. The exact refund amount is displayed on the page. If you purchased your subscription at a large discount, the refund amount may be zero.
