Remote Move Request: Exception has been thrown by the target of invocation

If you have a Exchange Hybrid deployment configured and attempt to create a new remote move request you may receive an ”Exception has been thrown by the target of invocation” error similar to the one below.

Here are a few things you can check in order to help troubleshoot this error:

• Have you enabled MRSProxy?
• Have you correctly set the EWS “External URL” (WebServicesVirtualDirectory)?
• Do you have a certificate installed that contains the DNS name used in the  EWS “External URL”?
• Are you entering the correct FQDN in the MRSProxy field of the new remote move request wizard?
• Are you using TMG/ISA to publish EWS? If so, ensure that you are not using authentication delegation on the following paths:
  • /ews/mrsproxy.svc
  • /ews/exchange.asmx/wssecurity
  • /autodiscover/autodiscover.svc/wssecurity
  • /autodiscover/autodiscover.svc
• Are you seeing “405” errors in the IIS log on the Exchange Hybrid server? If so, see KB2626696
