One of Windows 64-bit x86-64 editions is demanded to try Exchange Server 2007 (v8 and v8.1 supposing SP1 available). Still it's stated only for supported versions, so that trial version demands just 32 bits. Anyway there are now several companies that keep on using Exchange Server with thirty two-bit equipment. In order to turn to the new edition of the program they'll have to change the hardware. But hardware is not the single point. Due to the fact that Exchange Server 2007 doesn't allow in-place upgrades a number of companies using software of 2000 or 2003 will have to upgrade to the version of 2007.
Winter 2005 was the time when the small amount of testers got the chance to test Exchange 12, the coming beta version of Exchange Server 2007. Then in March 2006 the appearance of another developed beta edition was fixed. Developer team of the software made it accessible with TechNet Plus or MSDN subscriptions. And finally in April 2005 the company officially appointed the coming edition of the program to be called Exchange Server 2007.
Exchange Server 2007 is one of the Innovative Communications Alliance products. Below are the exchange host server roles fixed as the components of the software edition of 2007.
1. Mailbox or MB
It holdsr information and sorts mail. The role is also supposed to cater for Outlook clients MAPI access. Mailbox has its modification. To use multi-functional MSCS clustering of information stored on PC Clustered Mailbox role is used. Still it is impossible to combine other roles on the exchange server with this modification of Mailbox.
2. The Role of CA (Client Access)
Client Access is supposed to cater for the mail storage protocol admission with no links to MAPI. Applying internet browsers, mobile gadgets similar to ActiveSync or a third party mail agent is a different feature of the role.
3. The Role of Unified Message
Applying phone for the admission to mailboxes or calendars appears easy with this role. This type of server role needs supplementary equipment like a VoIP gateway aimed to let the role work properly.
4. Hub Transport or HT
Managing messages and classifying them due to the destination is the aim of this role. Exchange 2007 classifies the message amounts applying AD site info, that differs from the strategy of 2003 when admin set routing groups were used.
5. The Role of Edge Transport
That is the 1st step for inbox and the last step for outgoing. It’s really an important feature for some BES and it is mainly applied in perimeter nets as it provides mail quarantine. The role may as well work even if it is not connected with any Active Directory. It provides security even with nothing more than corporative network.
Tasks for Server Roles. User Interface
Server role idea actually fixes the server configuration for GUI and CMD. In Exchange 2007 each role that promises its exact actions is created to perform them. As for Mailbox, its feature is Get/Set-MailboxServer and the command to check whether it is installed is IsMailboxServer. CA role will then have the characteristics like Get/Set-ClientAccessServer and IsClientAccessServer. Hub Transport role with features Get/Set-TransportServer will be quickly proved with IsHubTransportServer. And operators like IsUnifiedMessagingServer and Get/Set-UmServer are applied to UM role.
