Just an fyi, did this with a batch script on a customer to remove the mailboxes form the extensions that should not get one. All were imported to give them a mailbox. I created the batch file that seemed to fail, i.e. adelete m1= XXXX. After this failure I changed it to adelete m1=xxxx m2=XXXX
This deleted every mailbox beyond may initiial starting point. Yes I was screwed. Found that a trailing (space) in the batch was needed.
I hope this helps someone in the future, as I am hosed. Did the python association and still see nothing for extension under Nupoint in users and services
