When using the "set forwarding" option in the Notes Migrator for Exchange | Administrator Driven Batch Migration | Notes Administrative Functions, the following message can be seen in the wlog file.
12:00:00 WARNING: [1395-31-96-00000000] Unable to set forwarding and/or disable foreign dirsync for user 'User_Name'
12:00:00 Unable to set MailAddressfirstname.lastname@example.org'.

If the Forwarding Address is already populated the Administrator Driven Batch Migration tool will not over-write existing values.
Please remove the forwarding address from Domino Administrator and re-run the forwarding action by taking the following steps:
1. Open Domino Administrator | People | Person Document.
2. Clear the Forwarding Address of any information.
3. Re-run the Administrator Driven Batch Migration tool to set forwarding.
