Standard: designed for the mailbox needs of small to midsize organizations. Also appropriate for non-mailbox roles in a larger Exchange deployment. This edition supports 1 to 5 mailbox databases.
Enterprise: designed for larger organizations that may require a greater number of mailbox databases. This edition supports 1 to 100 mailbox databases.
