How does the storage quota work?
Mailboxes in an account share the account quota. Quota tests are based on the sum of the storage used by all of the mailboxes in an account. When the sum of the storage used by all mailboxes in the account is at or over 100% of quota, notification will be delivered several times daily to all mailboxes in the account while the account is at or over 100% of quota. When the sum of the storage used by all mailboxes in the account is at 120% of quota, another notification is delivered to all mailboxes in the account and the MX servers begin rejecting email with a temporary failure code. Well behaved mail servers will queue the rejected email for some period of time from hours to several days at least. When the sum of the storage used by all mailboxes in the account has been over 120% of quota for 72 hours the MX servers reject email with a permanent failure code. Effective October 1, 2007: When the sum of the storage used by all mailboxes in the account has been over 100% of quota for 7 day
