- Brand new Outlook Web App optimized for tablets and mobile devices and also for desktops and laptops
- Unified Messaging in Exchange 2013 comes with same voice mail features in Exchange 2010, but the architecture change to have only two server roles made all the UM related components, services and functionality are now available in Mailbox Server Role
- Users can Move Mailboxes in batches where it has an option to send mailbox move reports as emails
- Lot of enhancement in the Database Availability Group like Managed Availability and Managed Store etc
- Exchange work load is a new feature in Exchange 2013 defined for the purpose of Exchange System Resource Management
- Exchange 2013 is completely rewritten so deploying and keeping exchange 2013 to up to date is now easier
- Data Loss Preventions is a new feature which allows to protective the company sensitive data and inform user of internal compliance policies
Question 2. What Is Exchange Admin Center?
Exchange Admin Center is the new web based Exchange Management Console for Exchange Server 2013, it allows for ease of use and is optimized for management of On-Premises, Online and hybrid Exchange deployments. EAC replaces Exchange Management Console and Exchange Control Panel, but ECP is still the url for Exchange Admin Center.
New features in Exchange Admin Center:
- List View – More than 20,000 objects can be viewed in EAC, where legacy ECP allows only 500 objects

- Public folders can be managed from Exchange Admin Center
- Long running process will be notified in the notification bar
- Role Based Access Control user editor can be done from EAC
- Unified Messaging tools like call statistics, and user call logs can be accessed from EAC
Question 3. Explain The Exchange 2013 Architecture?
Legacy versions of Exchange 2007 and Exchange 2010 released with 5 server roles, ie, Mailbox, Client Access, Hub Transport, Unified Messaging and Edge Transport server. Server role architecture has been changed in Exchange 2013 which released with only two server roles.
Mailbox Server role: It holds the same function of Mailbox, the client access protocols, Hub Transport and Unified Messaging server role in Exchange 2010
Client Access Server role: work as the client access server role in Exchange 2010, Exchange 2010 work as only stateless server, where it doesn’t do any data rendering, and nothing will be stored or queued in Client Access Server role. CAS offers all usual client access protocols: HTTP, POP and IMAP, and SMTP
Question 4. Why Exchange 2013 Architecture Has Been Changed With Two Server Roles?
Exchange 2007 and 2010 were architect with certain technology constraint that existed at that time, where CPU performance was the Key constraint when Exchange 2007 was released and to alleviate the situation Server roles were introduced. However server roles in Exchange 2007 and Exchange 2010 are tightly coupled
Nowadays, CPU horse power is less expensive and it is not a constrain factor, with that constraint lifted, primary goal for Exchange 2013 is simplicity of scale, hardware utilization and failure isolation. So Microsoft reduced the number of server roles to two as Client Access Server Role and Mailbox Server Role
Question 5. What Are The Benefits On The Architecture Change By Having Two Server Roles In Exchange 2013?
Having two server roles with Mailbox Server includes all the traditional components fount in Exchange 2010: the client access protocols, transport service, mailbox databases and unified messaging and the Client Access Server role to provide authentication, limited redirection and proxy services.
New architecture provides the below benefits:
- The Client Access Server and Mailbox Server become “Loosely Coupled”. All process and activity for a specific mailbox occurs on the mailbox server that holds the active database copy, eliminating concerns of version compatibility between CAS and Mailbox Server
- Version Upgrade flexibility – Client Access server can be upgraded independently and in any order.
- Session affinity to client access server role is not required – In Exchange 2013, Client access and mailbox components available on the same mailbox server, because the client access server simply proxies all connections to a specific mailbox server, no session affinity is required
- Only two namespace is required for Exchange 2013
Question 6. What Is Change Related To Mapi Access Using Outlook In Exchange 2013?
Two server role architects changed the outlook client connectivity behaviour; RPC is no longer a supported direct access protocol. This means that all the outlook connectivity must take place using RPC over HTTP knows as Outlook Anywhere. Because of this behaviour, there is no need to have RPC client access service on CAS which reduces two name spaces that required for site-resilient solution.
Question 7. Explain The Change In Outlook Client Connection Behaviour When Compared With Exchange 2010?
Outlook clients no longer connect to a server FQDN as they have done in all previous versions of Exchange. Outlook uses Autodiscover to create a new connection point comprised of mailbox GUID, @ symbol, and the domain portion of the user’s primary SMTP address. This change results in a near elimination of the unwelcome message of “Your administrator has made a change to your mailbox. Please restart.” Only Outlook 2007 and higher versions are supported with Exchange 2013.
Question 8. What Is Managed Store In Exchange 2013?
Managed store is the name of the newly rewritten information store process, Microsoft.Exchange.Store.Service.exe and Microsoft.Exchange.Store.worker.exe, it is integrated with Microsoft Exchange replication server to provide higher availability through improve resiliency. Also the Managed store has been architected to enable more granular management of resource consumption and faster root cause analysis though improved diagnostics.
Managed Store works with replication service to manage mailbox databases, which continues to ESE as DB engine, Exchange 2013 includes change the mailbox database schema that provides many optimization over previous versions of Exchange and Replication Services is responsible for all availability related to Mailbox Servers. This change provides faster database failover and better disk failure handling.
Question 9. What Is A Site Mailbox?
Site Mailbox is a new type of mailbox in Exchange 2013, where it improves collaboration and user productivity by allowing access to both documents in a SharePoint site and email messages in outlook 2013 using the same client interface.
Question 10. What Happened To Public Folders In Exchange 2013?
Special type mailbox called Public folder mailbox introduced in Exchange Server 2013, which will store both the hierarchy and public folder content. This provides an advantage of the existing high availability and storage technologies of the mailbox store. Legacy Public folder database concept not in exchange 2013 and Public Folder replication now user the continuous replication model as like Mailbox Database.
Question 11. How The Mail Flow Occur In Exchange Server 2013?
Due the architectural change, Mail flow in Exchange 2013 occurs via Transport Pipeline, it is collection of Transport services, connections, components and queues that work together to route the messages to the categorizer in the transport service on a mailbox server inside the organization.
Messages from outside organization enter the transport pipeline through a receive connector in the Front End Transport service on a client access server and then routed to the Transport Service on a Mailbox Server and the Mailbox Transport Delivery Service deliver the email to local mailbox database
Message from inside organization enter the Transport Service on a Mailbox Server in following ways, receive connector, Pick Up or Replay Directory, Mailbox Transport Service or Agent Submission. Those emails can be relayed to Front End transport service on Client Access Server using the Transport Service on Mailbox Server and sent outside
Question 12. Explain The New Transport Pipeline In Short?
Front End Transport Service in Client Access Server acts as a stateless proxy for all inbound and outbound external SMTP traffic for Exchange 2013 organization. It won’t inspect message content, only communicates with the Transport Service on a Mailbox Server, and doesn’t queue any messages locally.
Transport Service in Mailbox server is identical to Hub Transport server, it handles all SMTP mail flow for the organization, perform message categorization, and performs content inspection. It won’t communicate directly with Mailbox Database that task will be handled by Mailbox Transport Service. So the Transport Service routes messages between the mailbox transport service, the transport service and the front end transport service.
Mailbox Transport Service running on Mailbox server consists of two separate services: the Mailbox Transport Submission Service and Mailbox Transport Delivery Service.
Mailbox Transport Delivery Service receives emails from Transport Service on the local or different mailbox server and connects to the local mailbox databases using Exchange RPC to deliver the message
Mailbox Transport Submission Service connects to local mailbox database using RPC to retrieve messages and submits the messages over SMTP to the Transport Service on the local Mailbox server or other Mailbox Servers.
Question 13. What Are The Enhancements In Batch Mailbox Move On Exchange 2013?
Below are the enhancements on Exchange 2013 Batch Mailbox Moves:
- Multiple mailboxes move in large batches.
- Email notification during move with reporting.
- Automatic retry and automatic prioritization of moves.
- Primary and personal archive mailboxes can be moved together or separately.
- Option for manual move request finalization, which allows you to review a move before you complete it.
Question 14. What Are New Options Included In Exchange 2013 Related With High Availability And Site Resilience?
Managed Availability – Internal Monitoring and recovery are integrated to prevent failures, proactively restore services, and initiate failovers automatically or alert admin to take action.
Managed Store – Integrated with Microsoft Exchange Replication Service to provide higher availability
Multiple Databases per disk – Exchange 2013 supports multiple databases both active and passive on same disk.
Automatic Reseed – If a disk fails, database copy stored on that disk is copied from the active database copy to a spare disk on the same server.
Automatic recovery from storage failures
Lagged copies can now care themselves to a certain using automatic log play down
Single copy alert task is removed and included in the managed availability component
DAG networks can be automatically configuration by the system bases on the configuration settings, DAG now can distinguish between MAPI and Replication networks and configure DAG network automatically.

It is suggested that you use Cached Exchange Mode when you are using an exchange account for your work, as it eliminates all the reason to work offline. With Cache Exchange Mode, you can keep continuing working even if you are disconnected with the network. Cache Exchange Mode uses a folder file (.ost) and manages a synchronized copy of the items in all folder in the mailbox, when you are offline. As soon as you are connected to the network, it syncs your data automatically to the server without losing any data.
Question 27. Mention What Are The Roles In Ms Exchange 2013?
In MS exchange 2013, there are two roles Client Access Server and Mailbox Server.
Question 28. Mention What Is The Role Of Client Access Server?
The Client Access Server gives connectivity to various services like:
- Microsoft Office Outlook
- Outlook Web App
- Mobile devices
- POP & SMTP
- Accepts mail from delivers mail to other mail hosts on the internet
- Gives unified namespace, network security and authentication
- Handles all client requests for Exchange
- Routes requests to the correct mailbox server
- Allows the use of layer 4 (TCP affinity) routing
Question 29. Mention What Is The Role Of Mailbox Server?
Mailbox servers help in:
- e-mail storage
- Host public folder databases
- Host mailbox databases
- Calculate e-mail address policies
- Performs multi-mailbox searches
- Provide high availability and site resiliency
- Provide messaging records management and retention policies
- Handle connectivity as clients don’t connect directly to the mailbox services
- For given mailbox, it provides all core exchange functionality
- When a database fails over, it also fails access to the mailbox
Question 30. Explain What Are The Important Features Of Transport Pipeline?
Transport pipeline is made up of three different services:
Front end transport service: It does basic message filtering based on domains, connectors, senders and recipients. It only connects with the transport service on a mailbox server and does not backlog any messages locally
Transport service: It runs on all mailbox servers, and it handles SMTP mail flow. It helps in message categorization and content inspection. The transport services routes messages between the Mailbox Transport service, the Transport Service and Front End Transport service. This service does not queue messages locally
Mailbox Transport: This system includes receiving and sending SMTP to the transport service from mailbox using RPC (Remote Procedure Call).
Question 31. Explain What Is The Role Of Categorizer?
Categorizer performs following functions
Recipient Resolution: The e-mail address of the recipient is resolved to decide whether the recipient has got a mailbox in the Exchange Organization or an external e-mail address
Routing Resolution: Once the information regarding the recipient is resolved, the ultimate destination for the mail is routed, and the next hop are determined
Content Conversion: Once the mail has reached its determined address, the SMTP is converted into readable format like HTML, rich text format or plain text
Question 32. Explain The Term Dag (data Availability Group)?
DAG or Data Availability Group is a framework build is MS Exchange 2013. It is a group of upto 16 mailbox server that hosts a set of databases and provides automatic database level recovery due to failure of servers of databases.
Question 33. Mention How Many Types Of Delivery Groups Found In Ms Exchange 2013?
In MS Exchange 2013, there are five types of delivery groups
- Routing DAG
- Mailbox delivery groups
- Connector source service
- AD site
- Server List
Question 34. Explain How Message Is Delivered To The Mailbox Database In Exchange 2013?
In exchange 2013, after the message reaches the target mailbox server in the destination AD site, the transport service avails SMTP to carry the message to the mailbox. After that, using RPC, Transport Service delivers the message to the local mailbox.
Question 35. What Action Does Front End Transport Service Does?
Front end transport service does one of the following actions based on the number and type of the recipients
- For the message with a single mailbox recipient, choose a mail box server in the target delivery group and based on the proximity of the AD site, give preference to the mail box server
- For the message with multiple or several mailbox recipients, it uses the first 20 recipients to select a mailbox in a closest proximity or delivery group, based on the AD site proximity
- If the message has no mailbox recipients, it choose a random mailbox server in the local AD site
Question 36. Mention What Is The Function Of Mailbox Transport Submission Service?
Mailbox Transport Submission service does one of the following actions based on the number and type of recipients.
For the message having only one mailbox recipient, it chooses a mailbox server in the target delivery group and give priority to the mailbox server based on the AD site proximity
With multiple mailbox recipients, it uses first 20 recipients to choose a Mailbox server in the closest delivery group, based on the AD site proximity
If there is no mailbox recipient, select a mailbox server in the local delivery group
Question 37. How The Flow Of The Mail Is Tracked In Ms Exchange 2013?
To track message flow in MS Exchange 2013, Delivery Reports are used. It is applicable for Outlook and Outlook web only. However, Message Tracking Logs are also helpful to know the flow of the mail.
