2.2 Set 'Mailbox quotas: Prohibit send and receive at' to '2411520'

Information

Configure this setting to prevent users from sending and receiving e-mail messages after their mailbox size reaches the specified limit. To specify this limit, select the check box, and then type the size of the mailbox in kilobytes (KB) at which you want to prohibit the sending and receiving of e-mail messages and notify the user. You can enter a value between 0 and 2,147,483,647 KB (2.1 terabytes).

Rationale:

If users exceed their mailbox limits without warning, they may miss important messages requiring them to take immediate action to mitigate a security risk.

Solution

To implement the recommended state, execute the following PowerShell cmdlet:

Set-MailboxDatabase 'EXCHANGE01\Mailbox Database' -ProhibitSendReceiveQuota 2411520KB
