Chapter Summary

• Exchange Server 2003 recipients can be mailbox-enabled users, or mail-enabled users, contacts, public folders, or groups.

• Deleted Mailbox Retention and Deleted Item Retention are used to provide extra protection against inadvertent deletions, keeping you from having to restore from backup.

• Storage limits can be configured on individual mailboxes, on individual mailbox stores, or by mailbox store policies that can be applied to multiple mailbox stores.

• Access to distribution groups and address lists can be limited through permissions.

• Multiple storage groups can be used to implement different backup schedules.

• A storage group can contain five mailbox or public stores, and a single server can contain up to four storage groups.

• Recipient policies are used to apply e-mail addresses to the users that match the filter.

• A single offline address list can make multiple address lists available offline, and a storage group uses the same offline address list for every mailbox store in the group.

• A single set of transaction logs exists for all mailbox stores in a storage group, but each mailbox store has its own database files.
