Introduction to
Exchange 2003's Two Modes
To take advantage of all the new Exchange 2003 features you need to change
from mixed to native mode. Naturally, you must wait until there are no
more Exchange 5.5 servers before you make the switch.
Contents for Exchange 2003's Mixed and Native Mode
In mixed mode Exchange 5.5 and Exchange 2003 will be able to communicate
and co-exist in the same organization. Those old Exchange 5.5 servers will not understand some of the new
features of Exchange 2003, so you must not switch to native mode until you
de-commission the last Exchange 5.5 server.
The principle of mixed and native mode also applies to the Windows
operating system. NT 4.0, Windows 2000 and Server 2003 can all co-exist in
the same domain. When you have decommissioned all the old operating
systems the term to get the full set of features you 'Raise Domain Level' and
then 'Raise Forest level'. These Raise Level configurations are the
equivalent of switching to Native, its just that Microsoft use different
terminology to express the greater number of mixed domain combinations.
 Exchange Server 2007 is a complex topic, do you need practical hands on training? As an MCT trainer, I can thoroughly recommend
TrainSignal. In particular, I like the way
that TrainSignal cover all learning methods, instructor lead, video and of course text
material. You can either take one module, for example Exchange 2007 or go for a combination of modules.

Once you switch to Native mode you can take advantage of the following new
features of Exchange Server 2003:
- Rename your Exchange organization.
- Consolidate administrative groups and define
routing groups and administrative groups with greater flexibility.
- Move mailboxes between servers in different
administrative groups.
- Create Query based Distribution groups (See
more here)
- Create the InetOrgPerson object (See
more here)
- Routing groups can contain servers from multiple administration
groups.
- Routing uses the faster 8BIT MIME data transfer.
- In Native mode there is no need for any ADC' agreements with NT 4.0, so they can safely be removed.
- You can move servers between routing groups.

The SolarWinds Exchange Monitor
Here is a
free tool to monitor your Exchange Server. Download and
install the utility, then inspect your mail queues, monitor the Exchange
server's memory, confirm there is enough disk space and check the CPU
utilization. This is the real deal - there is no catch. SolarWinds
provides this fully-functioning product for free, as part of their commitment to
supporting the network management community.

Mixed mode is the default when you install the first Exchange 2003
server. This is how you make the switch: open the Exchange 2003 Administration program, then Right click the
Organization Name, Properties and select Change Operation Mode.
To save yourself a reboot, Restart the Microsoft Exchange Information
Store. How do you find the Information Store Service> - Administration
Tools, Services. (I also restart the other Exchange services at this point.)
If your situation is Exchange 2000 co-existing with Exchange 2003, then,
provided you have no plans to introduce any Exchange 5.5 servers, I would
switch to Native mode.
There is no 'Raise Domain' and Raise Forest' level as there is in Windows
Server 2003.
Logically, if you have a mixture of Exchange Servers they all need
to see and talk to one another, so the default is Native Mode. The
price you pay for compatibility is that the new features are unavailable
because the old Exchange 5.5. cannot understand or cope with the new
technology. So, as part of your migration plan set a date to 'go
native', thereby unleashing the full feature set of Exchange 2003.
