Agenda
• Improvements in Exchange 2013• A first look into Exchange 2016 • Exchange 2016 Preferred Architecture• Exchange Online future• Q&A

Exchange 2013(-ish)

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
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?

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)
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
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
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
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)
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
• …

Architecture
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
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)
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
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
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)
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
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!

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

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

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
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!
