Outlook Exchange profiles

[tomob]

I have recently converted to Outlook Exchange and all is well except the following;
I now have 2 sets of personal folders
one named just
Personal Folders
Within it its own inbox, Sent, Deleted Etc

the second one is labeled
Mailbox - Users Names

I want to remover the first one labeled "Personal Folder" and have only the one Labeled "Mailbox-Users Name"

I have not been able to find where to do this
