Exchange Server 2003

Exchange Server 2003 may be run on the Windows 2000 Server
if the fourth service pack has already been installed. It
may also be run on 32 bit Windows Server 2003. There is a
new disaster recovery feature that is even better than
before. It allows the server to experience less downtime.
The Exchange Server 2003 received some features form
Microsoft Mobile Information server as well. These include
Outlook Mobile Access as well as ActiveSync. Improved
versions of anti-spam and anti-virus were also included.
Management tools for mailboxes and messages have been
improved and Instant Messaging and Exchange Conferencing
Server are now separate products. There are two versions
available of Exchange Server 2003. These include the
Enterprise edition and the Standard edition. There are many
other features that are available on Exchange Server 2003.

Exchange Server 2007

When Exchange Server 2003 was released there were no
immediate plans as to what would happen to the product. A
2005 edition was dropped and it was not until the end of
2006 that the new version was released. Some of the new
features included integration of voicemail, improved
filtering, Web service support, and Outlook Web Access
interface. The new edition was run on a 64 bit x 64 version
of Windows Server. This increase the performance
significantly. There are quite a few improvements to
Exchange Server 2007. These include better calendaring,
improved web access, unified messages, and better mobility.
From a system protection standpoint there is more
clustering, antivirus, anti spam, and compliance included.
The IT experience is improved overall with a 64-bit
performance. Deployment is better; routing is simplified as
well as the command line shell and GUI.

There have been many changes and improvements to the
Exchange Server 2007 and it is better than ever. There are
no definite plans as to what Microsoft has in store for
Exchange Server but the next version will certainly be
better than ever.
