Error during Provision, The operation couldn't be performed because object <user> couldn't be found on <server> (4347915)

When performing the Migrator for Notes to Exchange (MNE) Provision operation, you may encounter the following error:

20:05:12 Description: The operation couldn't be performed because object 'example.com/Users/user1' couldn't be found on 'exchange01.example.com'.
20:05:12 Message: Unknown error 0x80131501
20:05:12 Error 80131501

The MNE Provision wizard has been enhanced to work in this type of environment by implementing a new parameter:

Multi-domain PowerShell scope option: The recipient scope of MNE's current PowerShell session can now be expanded to the entire forest (with Exchange 2010 or 2013 only), rather than limited to just the local domain. This feature is enabled and disabled by a new boolean program parameter in the [Exchange] section of Task Parameters and Global Defaults:

ViewEntireForest=[#]

Consider enabling this feature (ViewEntireForest=1) if you see errors like: The requested search root '[SearchRoot]' is not within the scope of this operation. Cannot perform searches outside the scope '[Scope]'. The feature is off (0) by default.
