During the beta of Office 365 for Enterprises, we received great

feedback from our customers and wanted to vastly simplify the process

for configuring Exchange in a hybrid deployment with Office 365. We are

introducing the Hybrid Configuration Wizard in Exchange 2010 Service Pack 2 to refine the deployment process as a result of that feedback.

What is the Hybrid Configuration Wizard?

The Hybrid Configuration Wizard consists of:

1. A new Exchange Management Console (EMC) wizard that guides you

   through the end-to-end process for configuring a hybrid deployment.

2. A set of Exchange Management Shell (EMS) cmdlets that orchestrate

   the configuration process (as always, the EMC executes these Shell

   cmdlets).

3. Improvements to the manageability of some of the underlying hybrid

   features (no more exchangedelegation.contoso.com or service.contoso.com

   domains – Yay!)

What does it do?

The hybrid configuration cmdlets take inputs from the wizard, analyze

the state of your existing on-premises and cloud organizations, and

calculate the required steps to correctly configure both organizations

correctly. You can learn more about this process here.

This friendly wizard replaces approximately 50 manual steps

with just a few inputs and several clicks of your mouse. Here are some

of the top tasks that the Hybrid Configuration Wizard will automatically

verify and configure for you:

1. Verifies that your on-premises and Office 365 organizations meet the prerequisites for a hybrid deployment.
2. Provisions your on-premises Exchange federation trust.
3. Creates mutual organization relationships between your on-premises and Exchange Online organizations.
4. Modifies e-mail address policies to ensure that mailboxes can be moved successfully to Exchange Online in Office 365.
5. Enables and configures free/busy calendar sharing, message tracking

   and MailTips for both your on-premises and Exchange Online

   organizations.

6. Configures secure mail flow between your on-premises and Exchange

   Online organizations. You can even choose to have the wizard

   automatically configure Exchange Online organization to route mail

   through your on-premises Exchange organization to meet any additional

   business or compliance requirements.

7. Enables support for Exchange Online Archiving for on-premises mailboxes for those customers that have chosen to include archiving in their Office 365 service plan.

Once the hybrid deployment configuration process is complete, the

following features are available between your on-premises Exchange

organization and Exchange Online:
