Migration Toolkit Error Trying to Mail Enable Exchange Mailboxes

Using the User Migration portion of the software.

Getting the following error condition when trying mail enable Exchange users:

(Migration Toolkit Log Begin)
--------------------------------------------------------------------
INFO - Creating mailboxes in Exchange started ...
INFO - Connecting to Exchange PowerShell ...
INFO - Connected to Exchange PowerShell.
ERROR - The term 'Enable-MailUser' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
INFO - EnableMailUser for User Steele, Matt with email MSteele@epiclp.com failed.
INFO - Creating mailboxes in Exchange completed.
--------------------------------------------------------------------

The documentation for the migration toolkit does not specify the rights that are needed for the "Username"  field on the Exchange configuration screen. So the customer assumed they should use a user with Domain Administration rights. They clicked the "TEST" button and the test passed. So they figured that they had chosen an appropriate user.

After the failure and error noted above, the customer then chose an user who was in the "Exchange Organization Management" role group. Using that user resolved this problem.
