When trying to run the Object Merge wizard the following errors occur.
[7559-120-6-00000001] Powershell Result: Error no snap-ins have been registered for Windows Powershell version 2
and [7938-120-1-00000000] Microsoft Exchange Management Powershell must be installed.
This issue was seen to occur in the following example environment:
This issue is caused using a 64 bit version of the Exchange Management tools.
The NME system requirements state that Windows XP, Vista, 2003, 2008 and Windows 7 are supported but only 32bit editions. No 64bit OS is supported for migrating to Exchange 2007.
Install NME on a 32bit OS and use the 32bit version of Exchange Management Tools for Exchange 2007.
Note that solution applies to migrations to Exhange 2007 only NOT Exchange 2010 where NME uses remote powershell instead of the management tools.
