top 10 reasons to upgrade to Exchange 2007
Unified messaging
-
voice mail system
-
Exchange 2007 can answer the telephone and record a message whenever the user’s phone goes unanswered or is busy
-
-
fax receiving
-
speech-enabled auto-attendant
-
An auto-attendant provides professional switchboard-like capabilities, with integrated speech recognition and the ability for callers to
-
search the company directory
-
Outlook voice access
-
Users can access their Exchange Server 2007 mailboxes using any telephone, hearing their e-mail and calendar entries and taking action on them using either speech or key pad commands
-
Local Continuous replication (LCR)
-
local log shipping
-
transaction logs of the production storage group are log shipped to the LCR location and then replayed into the LCR storage group
-
In the event of a disk failure or data corruption, the administrator can quickly switch to the copy database, offering an economical way to
achieve high availability
-
this could mean that you could potentially do exchange backups on a weekly rather than daily basis
-
LCR is supported in both Exchange 2007 standard and enterprise edition
-

Clustered Continuous Replication (CCR)
-
log shipping to another server
-
active/passive relationship
-
Shared storage is not required, so nodes can be potentially located in separate geographical locations (providing they are on the same subnet)
-
A traditional 2 node active/passive cluster (now called a “single copy cluster”) certainly has its benefits, but it also has one major drawback and that is you still have a single point of failure when it comes to Exchange databases.
-
CCR is only supported in Exchange 2007 enterprise edition; single copy clusters (or server clustering is also only available in the enterprise edition)
-
limitations:
-
the active and passive CCR servers need to be on the same subnet
-
since this uses a “majority node set” cluster, you will require also require the two CCR server to be running Windows Server 2003 Enterprise Edition (or Windows Server 2003 R2 Enterprise edition)
-
you’ll need a 3rd server to act as the “file share witness” (preferably the Exchange hub transport server)
-
you can only use one database per storage group for CCR
-
You cannot create a public folder database in a CCR environment if you already have more than one public folder database in your organization.
-
In a CCR environment, Microsoft recommends that you create no more than 30 storage groups and databases (one database per storage group) on the clustered mailbox server.
-
The cluster in which Exchange 2007 is installed cannot contain Exchange Server 200x, or any version of Microsoft SQL Server. Running Exchange 2007 in a cluster with any of these other applications is not supported.
-
Improved OWA
-
two-factor authentication support
-
-
works for: Word, Excel, Powerpoint and PDF attachments
-
-
-
can schedule the Out of Office Assistant messages ahead of time
-
separate internal and external Out of Office messages
-
Document access
-
OWA and ActiveSync act as a proxy for Microsoft Windows Sharepoint Services and Windows Server file share data
-
Can enable access to documents through OWA without directly exposing the document stores on the internet
-
this technology is called “LinkAccess”
Improved mobile messaging
-
ActiveSync (direct push)
-
self-service device wipe
-
if a device is lost or stolen, the user can clear the contents of the mobile device or reset the device’s password via Outlook Web Access
-
-
search for all mail content on the Exchange server; you’re not limited to the RAM available on your mobile device
-
flag messages
-
set the Out of Office message
Native 64-bit
-
more RAM capability
32 bit | 64 bit | |
---|---|---|
Win2003 Std | 4 GB | 64 GB |
Win2003 Ent | 64 GB | 1 TB |
-
larger cache
-
disk I/O reduced by 70% (due to larger cache)
-
in current storage environments, bandwidth is the limiting factor, not capacity
-
since bandwidth consumption has now been reduced by 70%, this enables us to use a smaller amount of larger capacity disks and/or use cheaper storage alternatives (such as iSCSI)
-
can fit 4 times more users
-
larger inboxes
-
Outlook AutoDiscovery
Edge/perimeter services
-
antispam built into the Edge Transport role
-
multi-engine antivirus, antispam and antiphishing can be configured via Exchange Hosted Filtering or Forefront for Exchange Server
-
Exchange Hosted Filtering and Forefront Security for Exchange Server are included with the Exchange Server 2007 Enterprise CAL license
Exchange Hosted Services
Exchange hosted services screenshots:
-
When the target Exchange server is unavailable, Exchange Hosted Services will just spool all of the incoming content, until the target Exchange server becomes available again:

Exchange Roles
edge transport role
-
this is the only perimeter role, which is typically deployed in a DMZ segment
-
functions: routing, hygiene (filtering, antispam, antivirus)
-
communicates with the internal hub transport role
-
-
Screenshots:
client access role
-
functions: OWA, ActiveSync, Offline address book
hub transport role
-
functions: routing, policies and compliance (eg journaling, message classifications rules)
-
demo of setting up a transport rule prohibiting one internal group (brokers) from communicating with another internal group (analysts).
-
demo of setting up a journaling rule for a specific user/group
-
demo of setting up a (server-side) message classification rule which is enforced to all users
-
-
need one hub transport for every AD site in which you have an Exchange server in
mailbox role
-
functions: mailboxes, public folders
unified messaging role
-
functions: voice messaging, fax, speech recognition
Sample flow
-
internet ⇒ outer firewall ⇒ edge transport role ⇒ internal firewall ⇒ hub transport role ⇒ mailbox role
