How to Configure Storage Quotas in Exchange Server 2010

 

Like previous Exchange versions, Exchange Server 2010 also supports Storage Quota on mailboxes and public folders. Exchange Server 2010 sends quota messages to the mailbox owners when size is exceeded. We can use Exchange Management Console or PowerShell to set the storage quota on mailbox level, thereby overriding quota set on database level.

There are three kinds of Quota setting that we can set for users:-

· Issue warning at (KB)

Range is from 0 through 2,147,483,647 KB. Exchange Server sends a warning message when mailbox size reaches or exceeds the specified value.

· Prohibit sent at (KB)

Range is from 0 through 2,147,483,647 KB. Users cannot send messages once the specified limit is reached.

· Prohibit sent and receive at (KB)

Range is from 0 through 2,147,483,647 KB. Users cannot send and receive messages once the specified limit is reached.

How to use Exchange Management Console to Configure Storage Limits on a Mailbox

1. Open the Exchange Management Console.

2. Navigate to Recipient Configuration and click on Mailbox.

3. From the detail pane, select the user for whom you want to set quota and open its Properties.

4. Click on the Mailbox Settings tab.

5. Click Storage Quotas and then its Properties.

6. Clear the Use mailbox database defaults check box, and enter the values in the following fields-

o Issue warning at (KB)

o Prohibit sent at (KB)

o Prohibit sent and receive at (KB)

7. Click Ok twice to save the settings.
