Export AD users to csv and import them to Exchange using shell

Question

I'm implementing Exchange 2013 on a Windows server 2012R@ network.
Now i want to import the users from the AD on the server into the Exchange server.
I've created a csv from the AD users, but there begins the problem.
I can't seem to get past some isseus..... The following script is where i'm at at the moment.
C:\Windows\system32> $list=import-csv "C:\users......." |foreach {new-mailbox $_.emailaddresss}
when i run this script in the shell of exchange i'm missing some parameters.
I need a password and a userprincipalname.
Can i include this in my script? And which password do i need?

Answer 1

Are you implementing Exchange 2013 into an existing AD environment or are you trying to import users that exist in a separate AD forest into your environment?
If you are implementing Exchange into an existing AD forest where the AD user accounts already exist, do use the Enable-Mailbox cmdlet instead as this adds a mailbox for an existing AD user.  The New-Mailbox cmlet will create a new AD user account,
which would be a problem if the accounts already exist.
If you are trying to bulk create mailboxes in a new AD environment where these AD accounts do not already exist, then you will need to create a password to assign to all the new accounts being created.
This link has information on creating new mailboxes using an input CSV and assigning passwords via the EMS.
