Hybrid Configuration Wizard fails to display digital certificates during hybrid deployment setup

Applies to: Exchange OnlineExchange Server 2016 Enterprise EditionExchange Server 2016 Standard Edition More

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


You run the Hybrid Configuration Wizard to set up a hybrid deployment between your on-premises Microsoft Exchange Server environment and Exchange Online in Office 365. However, you cannot select a digital certificate because the drop-down list in the wizard is empty.

Additionally, when you try to continue, you receive the following error message:
No valid certificate exists for the Hub Transport server(s).

CAUSE


This issue occurs if the Microsoft Exchange Service Host service on the hybrid server has stopped running.

SOLUTION


Start the Microsoft Exchange Service Host service on the hybrid server. To do this, follow these steps:
  1. Click Start, click Run, type services.msc, and then click OK.
  2. In the list of services, right-click Microsoft Exchange Service Host, and then click Start.
