How can I have AD automatically create mailboxes in exchange 2010 once the user is added to AD?

You can't. However if the AD user requires a mailbox why you you provision the AD account using Exchange mgmt so that the mailbox and AD account is created at the same time. James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

You can you Exchange Management Shell to do this. First you should set initial password and then create User/Mailbox in desired OU. here is the command : $password = Read-Host "Enter password" -AsSecureString New-Mailbox -Name Test User -Database First Storage Group\Mailbox Database -Password $Password -UserPrincipalName TestUser@AIC.LAN -Alias TestUser -DisplayName Test User -FirstName Test -Initials TU -LastName User -OrganizationalUnit Users

You can write a script in powershell which will look for AD accounts without smtp address, if script will find account it should create a mailbox for this account. Regards Remigiusz http://exchangeblog.pl
