"Format of the Exchange object version is wrong" error when you try to connect to Exchange Online in the Exchange 2010 Management Console

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 try to connect to Exchange Online through the Exchange Management Console (EMC) in Microsoft Exchange Server 2010, you receive the following error message:

The following error occurred while attempting to connect to the specified Exchange server 'PS.Outlook.com'

The format of the Exchange object version is wrong
Parameter name: ExchangeBuild

This problem causes the following conditions to occur:

  • You can't run the Hybrid Configuration Wizard that's included in the EMC.
  • You can't view the properties of recipients in Exchange Online from the EMC. (You can still manage recipients in the EMC, but you can't view the properties of the recipients.)
WORKAROUND
To work around this problem, do one or both of the following, as appropriate for your situation:

  • Run the Office 365 Hybrid Configuration Wizard. To obtain the wizard, go to http://aka.ms/HybridWizard.
  • To view the recipient properties for mailboxes in an environment that has directory synchronization enabled, use the Exchange admin center in Exchange Online or use Exchange Online PowerShell.
