This document summarizes a presentation on Exchange management. It discusses improvements in Exchange 2013 and 2016 such as enhanced document collaboration and search. It also covers the preferred Exchange 2016 architecture including the unbound namespace model and load balancing improvements. Finally, it briefly mentions the future of Exchange Online and tools for managing hybrid Exchange deployments.

4. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Exchange 2013(-ish)

5. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Standalone HCW
• Remove dependency on the on-
premises server for HCW bits;
similar to how oAuth config is
done today.
• Allows MSFT to be more agile >
shorter MTTR in case of issues
• Familiar look and feel

6. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Standalone HCW FAQ
• Will I be able to run it on Exchange 2010/2013/2016?
• Can I upgrade from Exchange 2010 to newer version?
• Can I opt out of the new HCW experience?
• Will I need to add any additional URL to my outbound proxy device?
• Will running the Stand Alone HCW change any of my settings?

7. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Support for IAAS
• As of May (announced at Ignite), MSFT supports the following
Exchange 2013 scenario on Azure IAAS VMs:
• Non-production
• Cluster Witness for stretched DAG
• Production; IF Azure Premium Storage is used

“Exchange on Azure is for people
with more money than sense”
~ Jeff Guillet (Exchange MVP)

9. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Why Azure (or not)?
• Limited use cases
• If you need hosted Exchange, better choose Office 365
• Can be costly:
• Premium Storage = +/- $60 per month for 512 GB
• Must use “DS-series”-VMs = +/- $800 per month for “common” server
• …

Exchange 2016

11. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Enhanced document collaboration

12. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Office Server?
• Exchange server now leverages
the Office web apps
• Delivered via Office Web Apps
infrastructure (must be separate
server!)
• Enables side-by-side viewing and
edit & reply capabilities for OWA
• Access to the document is
authorized by Exchange via an
OAuth token

13. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Search enhancements?
• Faster search (improvements based on behavioral analysis in Office
365)
• Outlook will now use server-side index when online (= more reliable
results)
• Suggested search terms (e.g. contact names)

14. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Other Productivity Enhancements
• Improvements • Inline previews for URLs / Videos
• Intelligent recipient selection and people search
• Inline reply
• One-click archive
• Common typos/suggestions
• Better way to handle/insert images
• Weather view
• Emojis
• Single line view
• …

15. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Architecture

16. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Key architecture changes
• Evolution from Exchange 2013
• Lessons learned from Office 365 (again!)
• Emphasis on preferred architecture;
• Combined MBX and CAS server roles
• Simple(r) coexistence with Exchange 2013;
• Easier Namespace planning / rollout

17. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
HA Improvements
• Faster DB corruption detection through new feature called “DB divergence
detection”
• Faster DB failovers (95pctile < 18 sec)
• “Loose Truncation”
• Support for ReFS
• New DAG Management service
• Replay Lag Manager now on by default;
• Auto play down when # of copies is insufficient
• Tied to disk I/O (disk health)

18. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
HA Improvements
• Get-MailboxServerRedundancy
• Determine which servers can/cannot be recycled/put into maintenance mode
• Limit excessive database moves
• Policies to limit/control human-initiated db moves
• Use New-SettingsOverride to control the policies (define peak times, # moves
per hour…)
• Admin can still override by specifying the
–SkipMoveSuppressionChecks parameter with Move-ActiveMailboxDatabase

19. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
HA Improvements ct’ed
• AutoReseed improvements
• 99,99 % success rate (!)
• In 2016 now also reseeds when single copy in the volume fails (instead of
volume failure
• Configuration-only-Reseeds:
• Source DB does not have to be online

20. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Security enhancements
• BitLocker support
• Enhancing Mailbox Audit logging (same as Office 365)
• Further improve DLP (new sensitive data types)
• eDiscovery and Archiving improvements;
• Public Folder Data
• Integration with Equivio (Machine Learning)

21. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Extensibility
• MAPI/CDO no longer supported (for real this time)
• Move to other protocols such as EWS or REST APIs
• REST APIs:
• Mail-, Calendar-, Contacts API
• Enable access across all sorts of platforms (mobile, web, …)
• Granular, scoped, permissions to user data

Preferred Architecture

23. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Namespaces
• Unbound namespace model
• Autodiscover
• Mail (or protocol-specific entries)
• OOS
• Bound namespace for OOS (former WAC)
• Use round-robin or GEO-DNS to distribute load across datacenters.

Load Balancing
• For Exchange: similar to Exchange 2013
• Exchange 2013 and 2016 can coexist in same array
• For Office Server: affinity required!

28. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
DAG Design
• Each DC in separate AD site (transport HA!)
• Increase DAG density before creating new DAGs
• Scale out instead of scaling up!
• Unbound, symmetrical DAG model spanning across datacenters
• No administrative access point
• Single network for replication and client traffic
• Utilize a third datacenter or Azure for Witness server placement,
if possible
• Deploy four copies, two copies in each datacenter
• Distribute active copies across all servers in the DAG
• One copy is a lagged copy (seven days) with automatic play down
enabled
• Native Data Protection is utilized

29. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Server design
• Physical deployment; use “commodity” hardware
• Dual-socket systems only (20-24 cores total, mid-range processors)
• Up to 196GB of memory
• JBOD storage
• Large capacity 7.2k SAS disks
• Battery-backed cache controller (75/25)
• Multiple databases/volume
• AutoReseed with hot spare
• Data volumes are formatted with ReFS
• Data volumes are encrypted with BitLocker

30. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Large mailboxes? Anyone?
• Exchange 2016 will support (very) large mailboxes (100GB+)
• Allows to eliminate PST files
• Removes need for (3rd party) Archiving solutions
• Outlook 2013 or higher can control cached data through slider

31. A W A R D W I N N I N G E X C H A N G E M A N A G E M E N T
Summary
• Architecture improvements bring a better HA story and improve
coexistence/migration scenarios
• Want to go low-cost? Take advantage of the Preferred Architecture
and leverage physical, commodity hardware like large capacity 7.2k
disks
• Keep It Simple S… (KISS). Less is more!
