Exchange Server 2007 - New Features against Server 2003
Let us take a look at some of the new features of Exchange Server 2007 - the ones that are not functional in Server 2003 and previous versions. The most interesting Exchange Server 2007 new features are:
Exchange Server 2007 - Exchange Management Shell: Offers a command prompt version of Server 2003's Exchange Management Console. This means you get more control over your network. The Exchange Management Shell helps you get more tasks done - as against the Exchange Management Shell Console.
The 64 bit Architecture of Exchange Server 2007: With 64 bit architecture, Exchange Server 2007 now has increased performance: more capacity to include several more databases and storage groups etc. Each storage group can contain 5 databases. However, the limit of databases per server is 50 - meaning no matter the resources on a server, it can hold only 50 databases, which is still a good number.
Automatic Handling of Exchange 2007 Hub Transport Server: This means less downtime. If a hub transport server is down due to congestion or any other failure, Exchange 2007 will automatically decide alternative routes for traffic. It does not require you to configure anything manually - to achieve automatic Hub Transport Server handling.
Support for Unified Messaging in Exchange Server 2007: Exchange 2007 can deliver all types of messages to user inboxes. The technology combines different messaging infrastructure so that all kinds of messages - mail, fax, and voice-mail can be accessed through a single inbox - using devices that include cell phones and other mobile devices as well as the regular workstations.
Exchange Server 2007 Exchange Web Services: One of the best Exchange Server 2007 new features, Exchange Web Services allows users to access their mailboxes remotely using HTTP protocol. Though personally, I would not recommend it - due to increased malicious activity on wireless - even for encrypted signals, the Exchange Server 2007 Web Services come handy when you are not at the workstation but need to interact urgently. I would suggest Exchange Web Services with SSL-3 encryption for even authentication.
The above are the most important Exchange Server 2007 new features. The following section informs about the major enhancements of Server 2007 over Server 2003.
