Do you have powershell installed? Did it create the OU structure in your AD?

Was this resolved? We have the same issue, same error. It seems to have happened after we upgraded to SP1 for Exchange 2007. It was working fine prior.

We're getting the same error but it is managing to create some of the users but not all.... if i go back through the wizard and re-run ita few more are created...... i have to keep doing this unti lthe full amount are created - annoying!! Any ides on what this could be???
