Reliability and Availability Improvements:
Continuous database replication support (aka Continuous Backup)
o
Using Local Continuous Replication (LCR) a 2nd copy of the
Exchange database can be kept and failed over to if the primary ones gets
corrupted or lost. Clustered Continuous Replication (CCR) provides similar
support to LCR but for a clustered Exchange server without the need for expensive
shared storage.
Log files decreased from 5MB to 1MB in size
o
This allows for better support for log file shipping, which is
used in LCR and CCR.
Management Improvements:
E-mail life cycle (ELC) management
o
Provides support to control how long certain messages are kept
until they are archived or deleted.
Managed Folders
o
These allow administrators to setup folders, which show up in
Outlook, that have policies applied to them. These policies can control how
long messages will be kept, if they will be archived, sent to another mailbox
and more. This is part of the ELC solution.
Policy Support
o
Allows for rules, similar to Outlook Rules, that can be used to
control what messages will be transmitted, copied, deleted, etc by Exchange.
Transport and ELC rules use this infrastructure.
Administrative control over Out-of-Office message generation
True resource mailbox support
o
Allows rules and permissions to be setup to control who can book
resources, workflow support for approval, reporting, and more.
Active Directory leveraged for Exchange routing
Message classification and policies
o
Can be used to control if a message can be forwarded, sent
outside the company, always encrypted and more.
Command line interface for all commands
o
Using the new PowerShell CLI, all Exchange functions can be automated.
Support for 50 storage groups and 50 databases per server
o
Allow for more granular database allocation.
Security Improvements:
Policy Support
o
Rules can be created that prevent certain messages from being
delivered, copy messages to a shared mailbox, and more.
Greater control over OWA
o
Can control what type of attachments can be viewed or accessed, if
secondary factor authentication is required, and more
Secured communication used by default
o
Servers within the same organization will always encrypt traffic
between each other.
Support for secured communications between business partners
o
Allows two organizations to encrypt e-mail between each other
with minimum setup.
