Collect Needed Information for an Exchange 2003 Hybrid Deployment


Applies to: Exchange Server 2010 SP1

Topic Last Modified: 2011-08-15

To configure a hybrid deployment between your on-premises Exchange organization and the cloud-based organization, you're going to need information about your current deployment. You might want to print this step so you can record your organization's information and have easy access to it as you go through the checklist.

This topic is meant to be read as part of the Microsoft Exchange Server 2003 and Office 365 Hybrid Deployment checklist. Information or procedures in this topic may depend on prerequisites configured in topics earlier in the checklist. To view the checklist, see Checklist - Exchange 2003 and Office 365 Hybrid Deployment.

We recommend using the Microsoft Office 365 Deployment Readiness Tool to analyze your existing Exchange organization and confirm that the prerequisites for a hybrid deployment are met. The readiness tool is integrated with the guidance provided in the Microsoft Office 365 Beta Deployment Guide and provides detailed assessments for Exchange Online, user identity and account provisioning, client and end-user experience, and many other areas.

You can use the following table to gather information about your existing organization that you're going to need before you get started. When you're working through your checklist, replace the example information that you see in the checklist with the information you've provided in this table. For example, if the external fully qualified domain name (FQDN) of your Exchange 2003 server is exchange.adatum.com, enter that FQDN in the "Value in your organization" field.


Description Example value in checklist Value in your organization

Active Directory forest root



Internal Exchange 2003 server host name



External Exchange 2003 server FQDN



Proposed internal hybrid server host name



Proposed external hybrid server FQDN



Outlook Web App URL



Primary SMTP namespace



User principal name domain

Microsoft Online ID domain



The following table lists new services that you configure as part of the hybrid deployment. For the values you provide in the table below, we recommend that you replace contoso.com with your domain name and use the example subdomains provided below. For example, if your domain is adatum.com, we recommend that you enter service.adatum.com in the "Value in your organization" field for the service SMTP namespace.


Description Example value in checklist Value in your organization

Important   You must not use the service tenant FQDN, specified below, as the service SMTP namespace. We recommend that you use service.<your domain>.



Internal Active Directory Federation Services (AD FS) server hostname



External AD FS server FQDN



Internal Active Directory synchronization server host name



Exchange federation trust namespace



On-premises Autodiscover FQDN
