  • All your mailboxes data is stored in the database, which is combination of EDB and STM file if you are on Exchange 2003 or lower edition and just the EDB file if Exchange 2007/2010. Storage Group is the collection of these Mailbox and Public Folder stores. All the databses in a single Storage Group share same set of log files. Here is very good article on that.

  • Storage Group:
    Managing Information store is one of your most important tasks as a Microsoft Exchange Server 2000/2003 administrator. The information store can contain storage groups, data stores, and databases.

    Storage groups allow you to group databases logically, giving you the option of managing an entire storage group (with all its database) or managing databases individually. When Exchange server is installed, the information store has a single storage group called First Storage Group. You can create additional storage groups as needed. Exchange Server 2003 Enterprise Edition is the most flexible. With the enterprise edition, you can create up to four additional storage groups as needed for a maximum of five storage groups per server (with one of the storage groups, called the recovery storage group, being reserved for database recovery operations).

    Mailbox Store:
    In Microsoft Exchange server, Data stores are containers for information. There are two types of data stores: mailbox stores, which store a server's mailboxes, and public folder, which store a server's public folders.

    Every Exchange server installed in the organization has an information store. The information store can hold multiple storage groups, and you can create multiple mailbox stores within the storage groups. Each mailbox store has database files associated with it.

    Mailboxes are the delivery location for messages coming into an organization. Mailboxes contain messages, message attachments, and other types of information that the user might have placed in the mailbox. Mailboxes are in turn stored in mailbox stores.
