The Archive Usage Limit tab lets you set a maximum size limit for all archives in the vault store.

When an archive has reached its usage limit, no more items can be archived in it unless the limit is changed. There is no immediate indication that an archive has reached its limit.

To monitor archive usage, see the reports from Vault Store Usage Reporter. See About Vault Store Usage Reporter.

Archive size limit. Set a maximum size for all archives in this vault store. If you want to use this setting, also set Limit archive usage to Enabled.

Inherited size limit. Shows the size limit that is set on the Site Properties: Archive Usage Limit property page. If you have selected Use Site setting for Archive size limit, archives in this vault store are limited to the size shown here.

Send notification to user when. Use these settings to control whether Enterprise Vault is to send mail to a user whose archive is approaching its maximum limit. You can control whether to send mail when a specific amount of space remains, or when a specific percentage of the available quota is reached.

The notification is triggered when an item archived from a mailbox takes the usage level over the threshold. The mail message is sent to the mailbox from which the item came. If an archive is shared, any mailbox that causes the limit to be exceeded receives a notification message.
