The Domain Proof of Ownership list in the Hybrid Configuration wizard is not populated in an environment that has Update Rollup 1 for Microsoft Exchange Server 2010 Service Pack 3 (SP3) or a later update rollup installed. You have to run the Get-FederatedDomainProof cmdlet in Exchange Management Shell to retrieve the list.
This issue occurs because a failure occurs after a new feature was added to Update Rollup 1. The new feature enables you to set auto discover by using the Set-HybridConfiguration cmdlet.
To resolve this issue, install the following update rollup:
