Deploying a Hybrid Infrastructure: Exchange Hybrid


The introduction of Office 365 has heralded a new era of productivity for organizations of all types and sizes, wherever they are in the world.

Office 365 provides small businesses with the same level of technology that was previously only affordable to enterprises. For many organizations this can equate to an increase in competitive advantage.

For enterprises Office 365 allows them to move operationally important systems such as e-mail out to the cloud with Exchange Online—to be maintained and optimized by Microsoft. This allows enterprises to focus on their line of business-enhancing technologies that will empower the organization to achieve greater levels of productivity and efficiency.

Exchange Online is by far the most popular component of Office 365 as it allows organizations of any size to offload their mailbox functionality to Microsoft and focus on their business—instead of having to worry about keeping servers operational and mail flowing.

While Office 365 also includes SharePoint Online, Lync Online, Office Web Apps, and Office Professional Plus, this book will focus specifically on Exchange Online.

What this book covers

In this book we will cover common scenarios for implementing Exchange Online ranging from simple one-way migrations to hybrid environments for co-existence with existing on-premise mail systems.

Chapter 1, Getting Started, covers the differences in Office 365 plans and the basics around obtaining an Office 365 subscription.

Chapter 2, Getting Familiar with the Office 365 Admin Portal, walks you through the administrative interfaces of Office 365 and how to add your first domain name.

Chapter 3, Integration Options for Small Businesses and Professionals, explains what options are available for customers of the "P1" plan to integrate with their on-premise systems.

Chapter 4, Integration Options for Enterprises, explains what options are available for customers of the Enterprise or Exchange only plans and integration with their on-premise systems.

Chapter 5, Preparing for a Simple Migration, helps subscribers of the small business plan to prepare their environment and existing mail systems to ensure that their migration to Exchange Online happens smoothly.

Chapter 6, Performing a Simple Migration, builds on Chapter 5 by explaining the process involved in performing a one-way migration to Exchange Online from a variety of mail systems.

Chapter 7, Preparing for a Hybrid Deployment and Migration, focuses on preparation to your Office 365 subscription and the integration components necessary for a Hybrid deployment.

What you need for this book

While the scenarios for small businesses and enterprise migrations may have different requirements they do share some common needs.

As the person performing the migration you will need to ensure that you have administrative access to your existing mail system, a high quality Internet connection, access to make domain name record modifications and patience!

Who this book is for

While Office 365 can make administration of enterprise-grade mail platforms simpler, readers of this book will still require an understanding of how e-mail systems work and familiarity with DNS and various mail platforms.

It is expected that readers will have at least basic IT skills in order to perform a migration to the small business plans. Readers who will be using the enterprise plans and looking at hybrid environments with Exchange Online will need a far greater level of familiarity with Active Directory and Exchange Server.

Ultimately this book can be categorized as being useful for small business owners with some level of technical understanding, through to corporate messaging administrators and IT consultants.


In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Does your monthly Internet download allowance cater for the mailboxes being downloaded back into the Outlook .OST file for each user?"

A block of code is set as follows:

$mbxlist = Import-CSV c:\csv\migrationbulk.csv
foreach ($line in $mbxlist) {
New-MoveRequest -Identity $line.alias -Remote -RemoteHostName -TargetDeliveryDomain -RemoteCredential $RemoteCredential

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

$mbxlist = Import-CSV c:\csv\migrationbulk.csv
foreach ($line in $mbxlist) {
New-MoveRequest -Identity $line.alias -Remote -RemoteHostName -TargetDeliveryDomain -RemoteCredential $RemoteCredential

Any command-line input or output is written as follows:

$cred = Get-Credential
