The most extensive Exchange 2003 reference found on the market today from one of the world's leading Microsoft server experts, Rand Morimoto. Written from the ground up exclusively for Exchange 2003--not a revision of an Exchange 2000 book. Based on the author's experience implementing Exchange 2003 in heavy-use corporate environments since Beta release 1. Contains hard-to-find intermediate to advanced coverage far beyond the competition's typical installation and set-up how-to's including planning, migration, security, disaster recovery, and vast troubleshooting tips. A complete reference targeted at intermediate to advanced users for help in managing the complicated and business-critical matters of e-mail, message databases, and ever-increasing mobile and remote system access.
