  4. New from E2007 to E2010 • Exchange 2010: On-Premise, Office365 or Hybrid • High Availability: Database Availability Groups (DAG) • Provides HA and disaster recovery • 30-second fail-over with simplified admin experience • Flexibility in storage choices (SATA disks, JBOD, etc.) • Replaces SCC, SCR, LCR, and CCR from E2007 • 64bit management tool support • RPC Client Access and Address Book service • Improved High Availability solution • Outlook MAPI connects directly to Client Access Servers • ExOLEDB, WebDAV and CDOEx are gone • “Entourage EWS” uses EWS

  5. Exchange Server 2010 Prerequisites • Active Directory • Windows 2003 SP2 GC server is installed in each Exchange Active Directory (AD) site • No hard requirement for Windows Server 2008 AD • Windows Server 2003 forest functional level • TIP: Windows Server 2008 RODC is cannot replace an GC • Exchange • All Legacy Exchange CAS and UM servers must have SP2 • Existing servers are Exchange 2003 SP2 or Exchange 2007 SP2. No Exchange 2000 or older servers. • To install Exchange 2010 on a machine • Windows Server 2008 SP2 or R2 64-bit editions (Std/Ent) • Windows Management Framework • .NET Framework 3.5 SP1 • Internet Information Services (IIS) • TIP: Use Windows Server 2008 R2 SP1 – Supported and Recommended • Hotfixes are rolled into SP1

  6. Exchange Server 2010 Updates • Latest SP1 update • Update Rollup 4for Exchange Server 2010 SP1 (14.1.323.6) • Re-Released July 27, 2011 (MSKB 2579150) • Latest RTM update • Update Rollup 5 for Exchange Server 2010 (14.0.726.0) • Released December 13, 2010 (MSKB 2407113) • See TechNet Wiki for more info -http://social.technet.microsoft.com/wiki/contents/articles/exchange-server-and-update-rollups-builds-numbers.aspx

  7. Setup – New Experience (SP1) • Install required Windows Roles and Features • RTM -> SP1 Upgrade • Setup.com /m:upgrade /installwindowscomponents

  8. Setup – New GUI Experience (SP1) • Apply strict split permissions security model • Typically used by large orgs that completely separate responsibility for management of Exchange and Active Directory between different groups of people • Removes ability for Exchange servers and admins to create Active Directory objects, such as users, groups and contacts, as well as the ability to manage non-Exchange attributes on those objects

  9. Outlook 2003 with Exchange 2010 • Fully Supported • Outlook 2003 by default does not turn on encryption for client – server communication • Outlook 2007/2010 – on by default • Encryption Options • Option 1: Turn of encryption for client communication • Set-rpcClientAccess –server{servername} –encryptionRequired $False • Option 2: Turn on encryption at the client manually or with Group Policies • MSKB 2006508 • Outlook 2003 performance – UDP on Exchange 2010 • Requires Exchange 2010 SP1 RU3 or above (c) 2011 Microsoft. All rights reserved.

  10. Upgrading to Exchange 2010 Internet Facing AD Site 2 Deploy E2010 Servers Upgrade Internet-facing sites FIRST • Start small • Gradually add more servers to support scale 4 Move Infra Pointers • Internet hostname switch • Unified Messaging switch • SMTP switch Internal AD Site Proxy https://autodiscover.contoso.com https://mail.contoso.com 5 Internet Move Mailboxes E200x Servers https://autodiscover.contoso.com https://mail.contoso.com https://legacy.contoso.com Legacy hostnames for old FE/CAS 3 1 Upgrade servers to SP2 • SSL cert purchase • End users don’t see this hostname • Used when new CAS tell clients to talk to legacy environments E200x Servers Upgrade Internal sites NEXT Decommission old servers

  11. Useful Tools and Scripts (c) 2011 Microsoft. All rights reserved.

  12. Preparation Tools Finding and solving problems before users do • Troubleshooting Assistant • Deployment Assistant • Pre-Deployment Assistant • Help determine the cause of performance, mail flow, and database issues • Provides customised instructions for upgrading to Exchange 2010 • Focus on overall topology readiness Remote Connectivity Analyzer • Simulate and test how a server responds to e-mail loads Best Practice Analyzer • Determine overall health of Exchange system and topology

  13. Exchange Server Deployment Assistant Exchange Server Deployment Assistant is your Best Friend (c) 2011 Microsoft. All rights reserved.

  14. Mailbox Assistants Troubleshooter (SP1) • Mailbox Assistants perform event-based and time-based functions (e.g., free/busy, resource booking, conversations, calendar repair, etc.) • Test-AssistantHealth can be used to verify the health of the Microsoft Exchange Mailbox Assistants services, to recover from health issues, and to report on the diagnosis or recovery action • Includes ResolveProblems parameter which can • Start the service if it is not running • Restart the service if it is hung or deadlocked for more than 15 minutes

  15. Database Log Growth Troubleshooter (SP1) • Troubleshoot-DatabaseSpace.ps1 detects excessive log growth issues and takes action • By default • Runs every 15 minutes to determine available free space • If free space < 25%, tools runs an algorithm to determine if excessive log growth is cause • If it is cause, the tool quarantines or throttles mailboxes causing excessive growth, as appropriate • Defaults defined in StoreTSConstants.ps1

  16. Database Latency Troubleshooter (SP1) • Troubleshoot-DatabaseLatency.ps1 used by SCOM, but can be used outside of SCOM as a schedule task • Defaults defined in StoreTSConstants.ps1 • Checks for database latencies above value of LatencyThreshold (default is 70 ms) • Checks disk’s transfer rate against read rate and read latency performance counters • Checks to see if any user is using more than one thread for duration of TimeInServerThreshold (default is 10 min)

  17. Database Latency Troubleshooter (SP1) • Disk’s transfers-per-second rate < DiskReadRateThreshold • Disk’s seconds-per-transfer rate > DiskReadLatencyThreshold • If both conditions are true, it indicates that disk has high latency under low load, which often means the disk is going bad and needs replacing • User using more than one thread for duration of TimeInServerThreshold • Mailbox quarantined for 6 hours

  18. Getting All Logon Statistics from Outlook • Use Get-LogonStatistics to retrieve data such as logon time, last access time, client version, and adapter speed • Get-LogonStatistics-Server <ServerName> • By default, Outlook 2010 and Outlook 2007 SP3 don’t transmit IP address, MAC address, username or machine name because it is considered PII (privacy) • Check “Enable troubleshooting logging” checkbox or add registry entry to Outlook client to get this info • HKCU\Software\Policies\Microsoft\Office\14.0\Outlook\CancelRPC\EnablePerfTracking • HKCU\Software\Microsoft\Office\14.0\Outlook\CancelRPC\EnablePerfTracking DWORD, Value: 0x00000028

  19. Deployment Considerations (c) 2011 Microsoft. All rights reserved.

  20. Deploying Exchange 2010 Topology decisions • Deploy Multiple Role Servers • CAS/HUB/MBX collocated • Even in Virtualised environments • Deploy an CAS array • Use hardware load balancer • Note: Virtual equivalents are also available (F5, Kemp, etc) • Look at flexible storage options • DAS, SAS, SATA – JBOD configurations • Leverage DAG for HA and DR • They are separate scenarios (c) 2011 Microsoft. All rights reserved.

  21. Namespaces and URLs Exchange 2003 Exchange 2010 Exchange 2007 Exchange Control Panel /ecp Unified Messaging /unifiedmessaging mail.contoso.com mail.contoso.com mail.contoso.com Outlook Web Access • /exchange, /exchweb, /public Exchange ActiveSync • /microsoft-server-activesync Outlook Anywhere • /rpc POP/IMAP Outlook Mobile Access • /oma Outlook Web Access • /owa Exchange Web Services • /ews Offline Address Book • /oab Unified Messaging • /unifiedmessaging Outlook Mobile Access • /oma Note: the /exchange and /public vdirs will provide a 301 redirect experience to /owa smtp.contoso.com • Autodiscover.contoso.com legacy.contoso.com E2003/E2007 services Autodiscover • /autodiscover Clients and SMTP servers

  22. Deploying SSL Certificates • Use “Subject Alternative Name” (SAN) certificate which can cover multiple hostnames • Minimize the number of certificates • 1 certificate for all CAS servers + reverse proxy + Edge/Hub • Minimize number of hostnames • Use “Split DNS” for Exchange hostnames • mail.contoso.com for Exchange connectivity on intranet and Internet • mail.contoso.com has different IP addresses in intranet/Internet DNS • Don’t list machine hostnames in certificate hostname list • Use Load Balance (LB) arrays for intranet and Internet access to servers

  23. 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 • Outlook clients connection for intranet MAPI access • Use New-ClientAccessArray and set-mailboxdatabase (c) 2011 Microsoft. All rights reserved.

  24. Switching to CAS2010 Preparatory steps • Obtain and deploy a new certificate that includes the required host name values • mail.contoso.com • autodiscover.contoso.com • legacy.contoso.com • Upgrade all Exchange servers to Service Pack 2 • Enable Integrated Windows Authentication on Exchange 2003 MSAS virtual directory (KB 937031) • Install and configure CAS2010 servers • Configure InternalURLs and ExternalURLs • Enable Outlook Anywhere • Configure the Exchange2003URL parameter to be https://legacy.contoso.com/exchange (c) 2011 Microsoft. All rights reserved.

  25. Switching to CAS2010 Preparatory steps, continued • Join CAS2010 to a load balanced array • Create CAS2010 RPC Client Access Service array • Ensure MAPI RPC and HTTPS ports are load balanced • Install HUB2010 and MBX2010 servers • Configure routing coexistence • Create Legacy hostname in DNS • Create Legacy publishing rules in your reverse proxy/firewall solution pointed to FE2003 / CAS2007 array • Use ExRCA to verify connectivity for Legacy hostname against E2003/E2007 (c) 2011 Microsoft. All rights reserved.

  26. Switching to CAS2010 The switchover autodiscover… mail… legacy… The switchover involves a minor service interruption • Update/Create Autodiscover publishing rule • Update Mail publishing rules • Update paths with new Exchange 2010 specific virtual directories • Switch: Move Mail… and Autodiscover… hostnames to point to CAS2010 array • Reconfigure CAS2007 internalURLs and externalURLs to now utilize Legacy namespace • Disable Outlook Anywhere on legacy Exchange • Test that CAS2010 is redirecting/ proxying to CAS2007 (externally and internally) TMG 1 2 2 E2010 CAS+HUB+MBX E200x SP2 Clients access E2010 through Autodiscover… and mail… 1 Redirection (legacy…), proxying, and direct access to E2003/E2007 2

  27. Client Access Upgrade • Clients access CAS2010 first • Four different things happen for E2003/ E2007 mailboxes • Autodiscover tells clients to talk to CAS2007 • HTTP redirect to FE2003 or CAS2007 • Proxyingof requests from CAS2010 to CAS2007 • Direct CAS2010 support for the service against BE2003 and MBX2007

  28. SMTP Transport Upgrade • - Follow this flow for each physical location • - Edge servers are optional • - Edge 2007 SP2 can be used with HUB 2010 Internet SMTP Servers Step 5: Switch Internet e-mail submission to Edge 2010 Step 4: Install Edge 2010 E2010 Edge E2007 Edge Step 3: Switch Edgesync +SMTP to go to HUB2010 E2010 HUB E2007 HUB E2003 Bridgehead Step 1: Upgrade existing E2003 and E2007 servers to SP2 Step 2: Install HUB and MBX 2010 E2003 Back-End E2010 MBX E2007 MBX

  29. Step 1: Introduce UM 2010 to existing dial plan Step 2: Route IP GW/PBX calls to UM 2010 for dial plan Step 3: Remove UM 2007 after mailboxes have been moved Unified Messaging Upgrade • IP PBXes and GWs • Configure to send all traffic to E2010 UM • E2010 UM will redirect to E2007 UM when necessary • Lync 2010 • With E2010 RTM, create new dial plan for E2010 UM users • Lync update: Lyncwill automatically talk to E2010 UM, which will redirect to E2007 UM when necessary • TIP: UM is not supported in a virtualised environment.

  30. Public Folders • Co-existence supported for Exchange 2010 and Exchange 2003/2007 • Outlook can access mailbox data from Exchange 2010 and public folder from Exchange 2003/2007 • OWA 2010 will allow access to public folders with replica on Exchange 2010 • Get-PublicFolderStatistics help take action • Move • Delete • Migrate to SharePoint • Public Folder DB can be located on Exchange 2010 that is part of a DAG but must use PF replication and not DAG technology.
