I needed to write a PowerShell utility to create Exchange mailboxes for new users in Active Directory. The utility needed to create the mailboxes, use different databases, retention policies, and take users from several Organisational Units along with users in child OUs. This utility is available to download from the Microsoft TechNet Gallery, PowerShell Gallery and GitHub. If you have any questions or comments, please leave them below.
