Cannot perform a second SetInfo when creating mailbox. (NETIQKB50942)

fact
Exchange Migrator 2.3

symptom
Cannot perform a second SetInfo when creating mailbox.

symptom
Error: 'ProcessHelperForMdb... failed to migrate object [/o=Org/ou=Administrative Group/cn=Recipients/cn=userName][HR=0x80070005].'

cause

The account performing the migration does not have permission to remove Microsoft Exchange attributes when merging on a mail enabled target account. The target account will be detected as being mail-enabled for one of the following reasons:

• Has been mail-enabled and thus granted SMTP addresses to function as a Contact.
• Has an existing target mailbox.
• Has the email address populated on the General tab of the user account properties in Active Directory, even if the account has no other mail attributes or tabs.

fix

Use another Administrative account to remove Exchange attributes from the target account and re-migrate, or grant the migration account enough permissions to remove Exchange attributes from the target account.
