Exchange Server 2007 is used only with Windows 64-bit x86-64 versions. It may be v8 as well as v8.1 with SP1. Anyway it concerns only full versions and a thirty two-bit trial version is open to anyone. Anyway a number of companies will have to change the equipment they are applying for they keep on working in Exchange Server with 32-bit hardware. Still that is not the only thing. Due to the feature that Exchange Server 2007 doesn't provide in-place upgrades a number of firms using programs of 2000 and 2003 will have to upgrade to the version of 2007.

Winter 2005 was the period when the certain number of people got the opportunity to test E12, the coming beta version of Exchange Server 2007. As fixed in Microsoft Exchange developers archives a developed beta version was let out in March 2006. It turned available with TechNet Plus and MSDN subscriptions. The next edition of the software was officially claimed to be named Exchange Server 2007 on April 25, 2006.

Exchange Server 2007 is one of the Innovative Communications Alliance developments. Below are the hosted exchange server roles fixed as the features of the program edition of 2007.

1. The Role of Mailbox

It keeps open folder data and arranges mail. The role is as well meant to provide Outlook clients MAPI access. Still there can be another variant. For clustering mailbox data with multi-functional MSCS Clustered Mailbox role is used. Clustered Mailbox can be never applied in combination with any different role on the exchange server hosting.

2. The Role of CA (Client Access)

Client Access is meant to cater for the mailbox service protocol admission with no links to MAPI. It as well lets use any comfortable services of Exchange 2003 FrontEnd hosting like ActiveSync (mobile device), POP3/IMAP4 e-mail clients and an OWA (Internet browser).

3. Unified Message or UM

UM makes it as well available to use phones to enter mail, note books or anything. This type of role demands additional equipment like an IP-PBX gateway in order to let the role function correctly.

4. Hub Transport or HT

Managing mails and classifying them according to the route of each is the task of Hub Transport. Well, while Exchange 2003 Bridgehead manages mail flow with admin fixed groups, this 2007 version applies AD site data to arrange it.

5. Edge Transport or ET

That is the first position for inbox and the finishing step for outgoing.
