Exchange 2007 - A user in a specific OU is unable to create a new mailbox

Hi guys, firstly here's my topology

Rootdomain.com
child1.domain.com
child2.domain.com

Exchange 2007 Cas1
Exchange Hub 1
Exchange mailbox1 - Child1-Database, Child2-Database

What i'm trying to do:
I'm trying to give a user in child1 domain the ability to create a new user and mailbox in a specific OU in a Child1-Database.
Also if this person already has these permissions, i'd like to see exactly what permissions they have.

Anyone has any ideas?
Thanks in advance..

You need to ensure that your user has Recipient Administrator Role for Exchange rights to create users with mailboxes and also mailbox management.

With Active Directory you will need to Delegate Permissions on a specific OU where you want these AD Accounts to be created upon creating the Mailbox.

hi Will

How can I check with PowerShell if they have this role?
Will SzymkowskiSenior Solution ArchitectCommented:
Yes you can do this via Powershell.

Get Exchange Recipient Administrators
Import-module activedirectory
Get-ADGroupMember -Identity "Exchange Recipient Administrators" | select name, samaccountname

Open in new window


To get AD Permissions on a speciifc OU
Get-ADPermission -Identity "ou=testou,dc=domain,dc=com" | Select Identity, User, Deny, Inherited, Rights

Open in new window
