One of the important tasks of an Exchange administrator is controlling mailbox sizes. It is very difficult to force users to voluntarily limit the size of their mailbox, so you have to use mail server quotas. Typically, mailbox quotas in Exchange Server are defined at the database level and apply to all mailboxes that are stored in this database. This is very convenient, since you know for sure that in a particular database all the boxes have the same data retention policy.

You can view the quota settings for the lonDB1 database with the command:

As you can see, the mailbox has three levels of size restrictions:

IssueWarningQuota—if the mailbox size is equal to or greater than the specified value, a warning is sent to the user of this mailbox;
ProhibitSendQuota—if the mailbox size reaches the specified value or exceeds it, the mailbox user on the Exchange server won’t be allowed to send new emails, and an error message will be displayed;
ProhibitSendReceiveQuota—if this value is exceeded, the user won’t be allowed to send new emails, and no more messages will be delivered to this mailbox. Messages sent to this mailbox will be returned to the sender with an appropriate error message (NDR).
