Collaborate Effectively
A familiar and rich Outlook experience across
clients, devices, and platforms
Exchange Server 2010 Prerequisites
•
Active Directory
•
•
•
•
Windows 2003 SP2 global catalog server is installed in each
Exchange Active Directory (AD) site
− No hard requirement for Windows Server 2008 AD
Windows Server 2003 forest functional level
Exchange
•
•
All Client Access Servers (CAS) and Unified Messaging (UM)
servers must have SP2
Existing servers are Exchange 2003 SP2 or Exchange 2007 SP2
•
•
•
•
Windows Server 2008 SP2 or R2 64-bit editions (Std/Ent)
Windows Management Framework
.NET Framework 3.5 SP1

Deploying SSL Certificates
•
•
•
•
Use “Subject Alternative Name” (SAN) certificate which can cover
multiple hostnames
Site resilience scenario
− If leveraging a certificate per datacenter, ensure that the
Certificate Principal Name is the same on all certificates
Don’t list machine hostnames in certificate hostname list
− Use Load Balance (LB) arrays for intranet and Internet access
to servers
Best practice: Minimize the number of certificates
− 1 certificate for all CAS servers + reverse proxy + Edge/Hub
− Additional certificate(s) if using Office Communications
Server (OCS)
Certificate Creation
1. Create a Certificate Request
file
2. Send Request file to
certificate authority you are
buying from
3. Use ImportExchangeCertificate to
activate newly acquired
certificate
4. Use EnableExchangeCertificate to
enable the certificate for use
with a particular service
New-ExchangeCertificate
-GenerateRequest
-Path
c:\certificates\request.req
-SubjectName “c=US,
o=contoso Inc,
cn=mail1.contoso.com”
-DomainName
mail.contoso.com,
autodiscover.contoso.com,
legacy.contoso.com
-PrivateKeyExportable $true
Deploying E2010
Topology Decisions—Split-brain DNS
•
•
•
Best Practice: Use “Split DNS” for Exchange hostnames used by
clients
Goal: Minimize number of hostnames
− mail.contoso.com for Exchange connectivity on intranet and
Internet
− mail.contoso.com has different IP addresses in intranet/Internet
DNS
Important: Before moving down this path, be sure to map out all
the hostnames (outside of Exchange) that you will want to create in
the internal zone
Deploying Exchange 2010
Topology decisions—CAS load balancing
•
•
•
OWA and EWS load balancing require ClientServer affinity
− Client-IP based Windows NLB or LB device using cookie-based
affinity
Tell Autodiscover where to send clients: Configure internalURL and
externalURL parameters and virtual directories
− Example: Set-WebServicesVirtualDirectory cas2010\ews* ExternalURL https://mail.contoso.com/ews/exchange.asmx
Tell Outlook clients where to go for intranet MAPI access
− Use New-ClientAccessArray and set-mailboxdatabase
Deploying Exchange 2010
Topology decisions—CAS load balancing
•
•
•
CAS AutoDiscoverServiceInternalUri property should be
set to NLB FQDN
Ensure the Web Services property InternalNLBBypassURL is set
to the Server FQDN
Configure virtual directory URLs according to this table:
Virtual Directory
InternalURL
ExternalURL
(Internet Facing AD Site)

(Non-Internet Facing AD
Site)
/OWA

Upgrading to Exchange 2010
Internet Facing AD Site
• Start small
• Gradually add more servers
to support scale
• Internet hostname switch
• Unified Messaging switch
• SMTP switch
Internal AD Site
Internet
Proxy
• SSL cert purchase
• End users don’t see this
hostname
• Used when new CAS tell
clients to talk to legacy
environments

and configured properly
Help determine the cause of performance,
mail flow, and database issues
