If I am understanding the question, you want to create Exchange 2007 mailboxes from a .csv file. If so, you will need to use the proper Exchange 2007 cmdlets. Which cmdlets you use depends on whether or not an Active Directory account exists.

If the AD accounts already exist, you can use:
Enable-Mailbox and Import-Csv

If the AD accounts do not already exist, you can use:
New-Mailbox and Import-Csv

Just make sure the .csv file is in the proper format as outlined below:

Alias, Name, UPN
