During a Group migration, the migration fails with the following error message:
“[FATAL_ERROR] Fatal error during migration process: Error during folders binding: The SMTP address format is invalid. “


The target name configured in the platform is not a correct SMTP address.


If you are migrating to the existing group or shared mailbox, enter a valid SMTP address in the Target Name field.
In any other cases, launch a PreProcessing task before the migration. Learn more about PreProcessing task here:
