Intro to Microsoft Exchange Server 2003

Exchange: To give in return for something received

Microsoft Exchange Server is an email based collaborative software solution. Designed for

exchanging information within a company and saving it server-side (e.g. Outlook, OWA,

IMAP, PDA).

The Required Specs Slide

Exchange 2003 comes in 2 version levels, Standard (S) and Enterprise (E). E has all the features of S, but many limits are eliminated and clustering requires E. E is designed for larger installations.

Exchange Requirements: P133, Win 2000 Srv, 256MB, 500MB on Exchange install partition, 200MB on System partition (these are unacceptable requirements, and I would NEVER run Exchange on this.)


The Exchange Servers I Buy

If a company is going to run Exchange, here are the minimums I would recommend on a server:

Pentium 4 1GB of RAM RAID 1 or 5 (2 or 3 HDs at min) 50GB of storage Antivirus is a requirement (current

favorite is TrendMicro)

Microsoft made it a lot easier for Exchange 2003 installs since the installation is a step by step process.
