How to Set Limits on Individual Mailboxes

All mailboxes that have a mailbox store have the same limit that is set on that mailbox store. However, you can configure individual mailbox limits to override the limits that you set for the mailbox store.

1.	Click Start, point to Programs, point to Microsoft Exchange, and then click Active Directory Users and Computers.
2.	In the left pane, expand Domain, and then expand Organizational units.
3.	Open the organizational unit that contains the mailbox that you want to configure.
4.	Right-click the mailbox, and then click Properties.
5.	Click the Exchange General tab, and then click Storage Limits. The Use mailbox store defaults check box is selected and the mailbox limits are shaded by default.
6.	Click to clear the Use mailbox store defaults check box, and then configure either the Issue warning at setting, the Prohibit send at setting, or the Prohibit send and receive at setting as required on this mailbox.
7.	Optionally, click to clear the Use mailbox store defaults under Deleted Item Retention to configure different settings for this mailbox.
8.	Click OK, and then click OK.
