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 Hybrid Configuration wizard that's available at http://aka.ms/HybridWizard. For more information, see Office 365 Hybrid Configuration wizard for Exchange 2010.
PROBLEM
When you run the Hybrid Configuration wizard, the wizard doesn't complete successfully, and you receive the following error message:
Cannot bind parameter 'Name' to the target. Exception setting "Name": "The length of the property is too long. The maximum length is 64 and the length of the value provided is 68."
CAUSE
This problem occurs if the domain name contains more than 50 characters. This is because the Hybrid Configuration wizard prepends "Hybrid Domain-" to the name. This adds 14 characters and causes a name that contains more than 50 characters to exceed the 64-character limit in an on-premises environment. If the Identity parameter of the remote domain contains more than 64 characters, this can cause the Hybrid Configuration wizard to fail.
STATUS
This is a known issue. Currently, there is no solution. Contact Microsoft Support for assistance.
