Configure storage quotas for a mailbox

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Recipient Provisioning Permissions" section in the Mailbox Permissions topic.

  1. In the console tree, navigate to Recipient Configuration > Mailbox.

  2. In the result pane, select the mailbox user for whom you want to configure storage quotas.

  3. In the action pane, under the mailbox user's name, click Properties.

  4. In <Mailbox User Name> Properties, click the Mailbox Settings tab.

  5. Click Storage Quotas, and then click Properties.

  6. In Storage Quotas, clear the Use mailbox database defaults check box, and then complete the following fields:

    • Issue warning at (KB)   Use this check box and use the corresponding text box to specify the maximum storage limit in kilobytes (KB) before a warning is issued to the mailbox user. The value range is from 0 through 2,147,483,647 KB. If the mailbox size reaches or exceeds the value specified, Exchange sends a warning message to the mailbox user.

    • Prohibit send at (KB)   Use this check box and use the corresponding text box to specify a prohibit send limit in KB for the mailbox. The value range is from 0 through 2,147,483,647 KB. If the mailbox size reaches or exceeds the specified limit, Exchange prevents the mailbox user from sending new messages and displays a descriptive error message.

    • Prohibit send and receive at (KB)   Use this check box and use the corresponding text box to specify a prohibit send and receive limit in KB for the mailbox. The value range is from 0 through 2,147,483,647 KB. If the mailbox size reaches or exceeds the specified limit, Exchange prevents the mailbox user from sending new messages and won't deliver any new messages to the mailbox. Any messages sent to the mailbox are returned to the sender with a descriptive error message.

  7. Click OK to return to the Mailbox Settings tab.
