Consider the following scenario:

  • You deploy Microsoft Exchange Server 2010 in an environment that already has Microsoft Exchange Server 2007.

  • Exchange 2010 and Exchange 2007 are separated by Microsoft Internet Security and Acceleration (ISA) Server 2006 or Microsoft Forefront Threat Management Gateway (TMG) 2010.

  • You try to move a mailbox from Exchange 2007 to Exchange 2010 by using the New-MoveRequest task on the Exchange 2010 Microsoft Management Console (MMC) snap-in.

In this scenario, the operation fails together with the following error message:

Error: MapiExceptionNetworkError: Unable to make connection to the server. (hr=0x80040115, ec=-2147221227)

Note The supported fix for Forefront TMG 2010 is included in Forefront TMG 2010 Service Pack 1 (SP1).


This problem occurs because ISA Server 2006 or Forefront TMG 2010 does not forward some error codes that are generated on the server-side remote procedure calls (RPC) in this scenario.
