Note The Hybrid Configuration wizard that’s included in the Exchange Management Console in Microsoft Exchange Server 2010 is no longer supported. Therefore, you should no longer use the old Hybrid Configuration wizard. Instead, use the Office 365 HybridConfiguration wizard that’s available at http://aka.ms/HybridWizard. For more information, see Office 365 Hybrid Configuration wizard for Exchange 2010.
If your on-premises Exchange organization is running Exchange 2007 or Exchange 2003, and if you want to connect your organization to Office 365 and your Exchange Online organization, you must install at least one on-premises Exchange 2013 or Exchange 2010 Service Pack 3 (SP3) server. This server is used for hybrid deployment connectivity that seamlessly connects your on-premises Exchange and ExchangeOnline organizations.
To avoid the additional cost of an Exchange 2013 or Exchange 2010 SP3 server license, you may qualify for a free Hybrid Edition product keyfor Exchange 2013 or Exchange 2010 SP3.
Obtain a Hybrid Edition product key
You can request a Hybrid Edition product key if all the following conditions apply to you:
- You have an existing, non-trial, Office 365 subscription.
- You currently do not have a licensed Exchange 2013 or Exchange 2010 SP3 server in your on-premises organization.
- You will not host any on-premises mailboxes on the Exchange 2013 or Exchange 2010 SP3 server on which you apply the HybridEdition product key.
To obtain a Hybrid Edition product key for your Exchange 2013 server or Exchange 2010 SP3 server, go to the Exchange hybrid productkey distribution wizard.
Note If the licensing tool does not work as expected, you can continue to receive Exchange licensing support at http://support.microsoft.com/ph/15834.
