I have a windows 2003 domain with 130 users. I will be installing exchange server 2007 and want to know what is the best way to create mailboxes for all the users.

Hi, There are various ways. You can export all the AD users info in some .csv file and then can use this CSV file to mail-enable all the users using Enable-Mailbox Powershell command in Exchange Management Shell. There are various examples available for this task. Plz search in google how to first export AD users info into a CSV File Have a look into thishttp://smtpport25.wordpress.com/2009/06/08/powershell-to-create-mass-mailboxes-in-exchange-2007-from-csv-input-file/ You will have to use Enable-Mailbox cmdlet instead of New-Mailbox for mail enabling existing AD users in Exchange 2007. Hope this helps. Regards,Laeeq Qazi|Snr Software Engineer(Exchange + Sharepoint + BES + DynamicsCRM) www.HostingController.com

I'd do this:Get-User -Filter {RecipientType -eq "user"}|Select-Object samaccountname, displayname |Export-Csv c:\users.csv -NoTypeInformationThen, sanitize the c:\users.csv file to remove all users you don't want. Save the file, and do a :Import-Csv c:\users.csv | New-Mailbox -Database <database name>Note that the Import.... line is untested :)Karl

Hi, [Quote] Import-Csv c:\users.csv | New-Mailbox -Database <database name>[/Quote] Karl for existing AD users Enable-Mailbox should be used. Regards, Laeeq Qazi|Snr Software Engineer(Exchange + Sharepoint + BES + DynamicsCRM) www.HostingController.com

Karl for existing AD users Enable-Mailbox should be used. You are absolutly correct - I know that and knew something looked wrong ;)Karl
