The target mailbox is not created for the existing target AD account.
Exchange Migrator is not able to update the home server property of an existing ADC created target account if the Exchange Migrator 2.2 SP1 option to Retain populated properties on the target object when merging accounts is selected.
Deselect the option Retain poplulated properties on the target object when merging accounts in the Specify Migration Options wizard. This option is not necessary in an IntraOrg migration as ADC has already populated the object with the same properties that EM will use.
As of the release of EM 2.2 SP 1 (2.21) Hotfix 27949 this option is now disabled in the Specify Migration Options wizard for IntraOrg migrations.
