This document provides an overview of Exchange 2013 architecture and roles. It discusses the Client Access server role which handles protocols and mail routing. It focuses on the Mailbox server role which hosts mailbox databases and stores mail data. It also covers managing Exchange 2013 through tools like the Exchange Management Shell and tasks like patching.

LICENSING EDITION
 License Edition:
 Exchange Server 2013, Standard Edition
 Exchange Server 2013, Enterprise Edition.
 Client Acess License (CALs):
 Standard CAL: offers standard e-mail functionality from any platform. The license is for typical Exchange and Outlook usage
 Enterprise CAL: offers functionality such as integrated archiving, compliance features, and information-protection capabilities.
 The CAL is an add-on to the Standard CAL, so both licenses need to be purchased!

5.  Don’t support for Outlook 2003
 RPC/TCP access for Outlook clients
 Transport service integrated
 Unified Messaging service
 Managed folders
 Anti-malware

ACTIVE DIRECTORY PARTITION
 Schema partition:
 Contain all objects and properties that are available
in Active Directory
 There is only one schema partition in the entire
Active Directory forest
 Exchange Server 2013 adds a lot of new objects and
attributes to Active Directory that make it possible to
gain functionality
 Configuration partition:
 Contain all nonschema information is stored
 Information stored in the configuration partition is
Exchange Server information (accepted domain
information, Rule and policy information)
 Domain partition:
 Contain all domain-specific information is stored
 User objects, contacts, and security and distribution
groups are stored in the domain partition

9. LOAD BALANCING
 With Exchange 2010:
 Configuration on a KEMP Load Balancer was quite
simply and easily accomplished.
 You can use the Exchange templates provided by KEMP,
or perform the configuration manually,
 The requirement: one for RPC/MAPI, one for HTTPS
(443), optionally redirection for HTTP (80) requests to
HTTPS (443).
 With Exchange 2013:
 Layer 4 Virtual Service for traffic coming in for HTTPS
(443) and Round Robin
 Just only Layer 7 load balancing have ability perform
health checking for individual Exchange 2013 web
services and to take advantage of intelligent features

FOCUS ON CAS

11. CAS 2013
 The CAS in itself does not perform any processing with
respect to mail data
 If a CAS goes, all connected clients need to re-
authenticate against another Client Access
serverReceive request from Internet to the CAS is
using the regular port 443, but that the proxied
request to the Mailbox server is using port 444
 Multiple CAS just only handle workloads, not relative
with Load-Balancing solutions
 The Client Access server comprises three different
components:
 Client access protocols (HTTP, IMAP4, POP3)
 SMTP
 UM call router

12. CLIENT ACCESS SERVER 2013
The Death of RPC/TCP
 The HTTPS connection is then terminated on the
Mailbox server— on IIS on the Mailbox server, and
the AppPool on the back end decapsulates the RPC
traffic from the HTTPS stream
 Since the Outlook clients now connect to the
correct Mailbox server, it is no longer necessary to
use the RPC Client Access server array
 Exchange 2010: The FQDN of the CAS array was also
the server name that was visible in the Outlook
profile.
 Exchange 2013: The FQDN being used in the
Outlook profile has been replaced with the mailbox
GUID

13. CLIENT ACCESS SERVER 2013
Autodiscover
 Autodiscover works by an XML request sent from the
Outlook client to the Client Access server.
 The Client Access server then accepts the request
and proxies it to the Mailbox server. The Mailbox
server gathers all the required information and
returns this as an XML package to the Outlook client.
 The request is sent once an hour to determine if
there are any changes in the Exchange configuration
 When a Client Access server is installed, a service
connection point is also created in Active Directory
 A service connection point has a GUID (Global
Unique Identifier)

14. CLIENT ACCESS SERVER 2013
Load Balacing
 With a layer-4 load balancer, the load balancing takes
place on the network layer. An incoming connection
is accepted and distributed across multiple Exchange
2013 Client Access servers
 The Client Access server in turn accepts the
connection, and after authentication, the connection
is forwarded to the appropriate Mailbox server.
 If one service on the Exchange 2013 Client Access
server fails, the load balancer only detects that the
Client Access server in general has failed and will
initiate a fail-over to another Client Access server

15. CLIENT ACCESS SERVER 2013
Routing Mail
 With a layer-4 load balancer, the load balancing takes
place on the network layer. An incoming connection
is accepted and distributed across multiple Exchange
2013 Client Access servers
 The Client Access server in turn accepts the
connection, and after authentication, the connection
is forwarded to the appropriate Mailbox server.
 If one service on the Exchange 2013 Client Access
server fails, the load balancer only detects that the
Client Access server in general has failed and will
initiate a fail-over to another Client Access server

FOCUS ON MBX

17. MAILBOX SERVER 2013
 One Exchange 2013 Enterprise Mailbox server can host
up to 100 mailbox databases
 When you install a Mailbox server, a new mailbox
database is automatically created on the boot- and
system disk (C:)
 The recommended maximum database size for a
normal Exchange 2013 Mailbox server is 2TB (Up to
16TB) when you have multiple copies of the mailbox
database
 E01 (transactional processing of information)
 E00.chk (a checkpoint file that keeps track of the
transactions still in the log files)
 E01res00001.jrs - E01res0000A.jrs (are temporary log
files reserved by Exchange Server in case of disk-full
problems)
 E01tmp.log
MAILBOX DATABASE

18. MAILBOX SERVER 2013
 For every mailbox database that is mounted on an
Exchange 2013 Mailbox server, a new Information
Store worker process is spawned and responsible for
this particular database
 If you have an Exchange 2013 Mailbox server with 25
mailbox databases mounted, and one of those
databases crashes, including the Information Store, the
other 24 mailbox databases are not affected
Microsoft Exchange Information Store

19. MAILBOX SERVER 2013
 Called “the public folder mailbox”
 The public folders are now stored in mailbox databases
 The public folders consisted of two parts: Hierarchy
and Content.
 Exchange Server 2013
 The hierarchy: is now stored in a new type of
mailbox “the public folder mailbox”
 The Content: contain all public folders
